Abstract:

The Brachistochrone problem, which describes the curve that carries a particle under gravity in a vertical plane from one height to another in the shortest time, is one of the most famous studies in classical physics. There is a similar problem in track cycling, where a cyclist aims to find the trajectory on the curved sloping surface of a velodrome that results in the minimum lap time. In this paper, we extend the classical Brachistochrone problem to find the optimum cycling trajectory in a velodrome, treating the cyclist as an active particle. Starting with two canonical cases of cycling on a sloping plane and a cone, where analytical solutions are found, we then solve the problem numerically on the reconstructed surface of the velodrome in Montigny le Bretonneux, France. Finally, we discuss the parameters of the problem and the effects of fatigue.

Abstract:

The Government of Jakarta is trying to reduce the traffic volume by launching many new rail-based public transportation modes in this Jakarta Capital Region, one of them is Jakarta LRT. There are so many special things at the LRT Velodrome Station, for example the strategic location of Velodrome, the Jakarta International Velodrome stadium, integrated with Transjakarta transportation mode, etc. Even though the Jakarta LRT is the new transportation mode, but the Jakarta LRT only used by few people, because the route is still too short only 5,6 km (Pengangsaan Dua to Velodrome). So, this research discuss about the preference of passengers in using Jakarta LRT as the option for their daily transportation. The analysis of data obtained in this research by using the “Importance Performance Analysis” method, and analyzed the validity and reliability by using SPSS 24 program. The results of people’s preferences by using Jakarta LRT in this research are located in quadrant II that have a good performance on passengers satisfaction, so the performance must be maintained. And the items that needs to be improved for the efficiency and effectiveness are located in quadrant I that requires the high priority on its performance

Abstract:

The original roof, finalized in 2003 did fail shortly after the installation process during a thunderstorm. The complete membrane was destroyed but the main masts were still in place and not damaged. It was then decided to replace this roof by a more redundant system, but with the same appearance. Main goal for the redesign was to avoid any modification on the main masts, and ideally no replacement of the main suspension cables. The design was started with the evaluation of different types of large scale cable nets, to achieve a system with a comparable load bearing behaviour. It ended up with a pentagon and hexagon pattern, forming a similar shape like the previous membrane roof, and so with a comparable geometric stiffness.

Abstract:

This paper presents a training monitoring system for cyclist that is based on the technology of wireless sensor networks (WSNs). A stable and reliable wireless cyclist monitoring system is vital to establish a smart and efficient sports management program. A training monitoring system has been developed and tested in a real cyclist training environment in a velodrome. The system is designed is such a way that the packet loss rate is minimum. Using TelG mote as the basis, customized sensor nodes that function as a forwarder node and the relay nodes are developed to form the WSN. This WSN is linked to the cloud network on the Internet. The cloud network is then established and end users application for data accessing is designed. Several experiments have been conducted in a real scenario in a velodrome to measure the reliability of the system architecture. It is shown from the experiments that the proposed system is reliable even when the cyclist is moving at a high speed. The packet loss is less than 2% which does not give a huge impact to the data transmission.

Abstract:

Aerodynamic drag constitutes over 96 per cent of the overall resistance to motion for a typical rider and bicycle combination. Although the rider of a typical track pursuit bicycle constitutes approximately two-thirds of the overall aerodynamic drag, the bicycle itself still contributes one-third. Any reduction in the drag generated by the bicycle can therefore have a significant effect on the maximum attainable speed for a given power input, and thus the time to cover a given race distance. At the same time it is important to optimize the riding position so as to minimize both the rider drag and any interference effects between the rider and bicycle. Cross-wind conditions are also of vital importance to cyclists. For most conventional tubular framed bicycles any wind on a velodrome will result in significantly slower times due to the increased drag. For a properly designed monocoque aero bicycle, however, a cross-wind can mean faster times on a velodrome due to a ‘sail’ effect being generated. The LotusSport monocoque pursuit cycle has been designed and developed to gain maximum benefit from aerodynamic drag reduction and sail effects. It was produced for, and used at, the 1992 Barcelona Olympic Games where it was ridden to the gold medal in the 4000 metre individual pursuit event.

Abstract:

Background/Objectives: This study introduces the importance of the aerodynamics to prosthetic limb design for athletes with either a lower-limb or upper-limb amputation. Study design: The study comprises two elements: 1) An initial experiment investigating the stability of outdoor velodrome-based field tests, and 2) An experiment evaluating the application of outdoor velodrome aerodynamic field tests to detect small-scale changes in aerodynamic drag respective of prosthetic limb componentry changes. Methods: An outdoor field-testing method is used to detect small and repeatable changes in the aerodynamic drag of an able-bodied cyclist. These changes were made at levels typical of alterations in prosthetic componentry. The field-based test method of assessment is used at a smaller level of resolution than previously reported. Results: With a carefully applied protocol, the field test method proved to be statistically stable. The results of the field test experiments demonstrate a noticeable change in overall athlete performance. Aerodynamic refinement of artificial limbs is worthwhile for athletes looking to maximise their competitive performance. Conclusion: A field-testing method illustrates the importance of the aerodynamic optimisation of prosthetic limb components. The field-testing protocol undertaken in this study gives an accessible and affordable means of doing so by prosthetists and sports engineers. Clinical relevance Using simple and accessible field-testing methods, this exploratory experiment demonstrates how small changes to riders’ equipment, consummate of the scale of a small change in prosthetics componentry, can affect the performance of an athlete. Prosthetists should consider such opportunities for performance enhancement when possible.

Abstract:

This article describes the design and development of an upper-limb prosthesis for a current elite level paracyclist that was conceived for use in the 2020 Paralympic Games. The prosthetic limb was intended specifically for use in cycling time trial events. These are held on the road and in the velodrome whereby the athlete rides using a tucked aerodynamic position. The prosthesis was developed using computer aided design software and an extensive use of the 3D printed manufacturing process. The resulting technical note illustrates the design methodology and manufacturing considerations for a high performance form of assistive technology. However, it results in a solution that challenges the traditional aesthetic of prosthetic limbs intended for sport and physical activity.

Abstract:

Recently, several researchers have highlighted the difficulty with the binary terms “insider–outsider” within qualitative research. We similarly critique the insider/outsider binary in this article, but offer an alternative by utilizing Bourdieu’s theoretical concepts of capital, habitus, and field to compare two researcher’s ethnographic accounts of researching sports facilities in New Zealand. One of the ethnographers, D.S., describes himself as closer to an outsider than an insider in the context of the velodrome he was examining, while R.K. describes herself as an insider in the field of gymnastics. Through comparing their accounts, we show how the language of insider/outsider can be limiting. Instead, we argue that Bourdieu’s framework provides a more nuanced account of researcher positionality that moves beyond the insider/outsider binary, while affording insights into the reflexive and fluid researcher performances that shape the ethnographically researched field.

Abstract:

This paper presents the full derivation of an analytical model for track cycling. The model takes into account the unique aspects of track cycling associated with riding around a velodrome. These include, riding upon a banked track and the resulting tyre scrubbing effects, and the tipping motion of a cyclist passing through a corner with the resulting centripetal forces. Validation was provided using SRMTM power crank data and split times obtained for an elite national cyclist in a 4 km pursuit competition. Results have shown the model to over-predict cyclist performance with a discrepancy of 0.7 s in a finals event and 4.3 s, less than 2% error, in a qualifying race. It is believed this may be attributable to discrepancies in atmospheric variables. However the model has proved capable of predicting the velocity increase, specifically associated with track cycling, as a cyclist passes through a bend. The model is useful for analysis of the physics of track cycling, and can be used to quantitatively predict performance dependent upon bicycle efficiencies, tyre type and venue conditions, in a racing scenario.

Abstract:

The double-shell structure under high temperature will lead to structural changes in material properties. Thermal expansion causes the production of thermal stress of the additional constraints bar, whose security research is the aim of this paper. The paper chooses Laoshan Velodrome Olympic venues as the research object, dividing the temperature zones of shell structure, and conducting the FDS simulation temperature field. The internal temperature of structural elements of computational shell in various zones will be in accordance with the first constant load and dead load after warming loading method to give a finite element analysis and give an evaluation of the safety of shell structure. The results show that: the temperature of the fire scenarioⅠis significantly higher than that of the fire scenario Ⅱ.We selecte the temperature of the fire scenario Ⅱ as the temperature load, and find that the local damage of six bars in the high-temperature zone occurs, which won’t cause structural damage to the whole structure. Therefore, these 6 bars need to be sprayed with fire retardant coating.

Abstract:

Dalam analisis pondasi, besarnya daya dukung dan penurunan yang terjadi merupakan dua hal terpenting mengingat fungsinya sebagai distribusi beban sebuah konstruksi ke tanah. Pondasi harus memiliki daya dukung yang mampu memikul beban diatasnya sehingga sistem tranfer beban ke tanah dapat berjalan dengan tetap mengontrol terhadap penurunan ijin untuk menjaga kestabilan konstruksi di atasnya. Analisis ini bertujuan untuk menghitung besarnya daya dukung dan penurunan yang terjadi pada pondasi bored pile proyek Jakarta LRT-Corridor 1 (Phase 1) Kelapa Gading-Velodrome-Package P 102 dengan metode elemen hingga menggunakan perangkat lunak Plaxis 3D dengan semua tipe mesh. Berdasarkan analisis yang telah dilakukan, daya dukung ultimate bored pile dengan metode interpretasi loading test dengan metode Davisson memberikan nilai 816 ton, metode Mazurkiewich 950 ton dan metode Chin 761 ton. Analisis Plaxis 3D menghasilkan daya dukung 400 ton dengan metode Davisson, 816 ton dengan metode Mazurkiewich dan 766 ton dengan metode Chin. Sehingga dapat disimpulkan bahwa nilai daya dukung berdasarkan Plaxis 3D lebih besar daripada hasil loading test di lapangan. Sedangkan penurunan yang dihasilkan oleh analisis Plaxis 3D dengan mesh medium memberikan nilai yang paling mendekati hasil pengujian di lapangan.

Abstract:

The aim of this study was to analyse the acute effect of biomechanical foot orthotics on drag area (ACd) and perceived comfort in elite cyclists affected by a lower limb length inequality (LLLI) in TT position. Twenty-nine cyclists performed two discontinuous incremental exercises (before and after orthopaedic correction) using their personal TT bicycle and equipment on a 250-m indoor velodrome. The ACd was unchanged in both the test group (TG) (‑0.5%, p = 0.707) and the control group (CG) (-1.4%, p = 0.276), whereas the perceived comfort was improved in the TG (+6.2%, p = 0.002) and stabilised in the CG (+0.7%, p = 0.546), after the fitting of the foot orthotics. Pelvis movements were decreased (small effect size) in the TG (-6.2%, p = 0.093, ES = 0.251), whereas they were increased (small effect size) in the CG (+5.2%, p= 0.159, ES = 0.215). TT position was slightly improved by compensating for a LLLI, as the ACd was stabilised and the level of comfort was improved. Thus, cyclists affected by a LLLI are recommended to compensate with foot orthotics in order to improve their level of comfort and consequently their performance in TT position.

Abstract:

In cycling, performance models are used to investigate factors that determine performance and to optimise competition results. We present an innovative and easily applicable mathematical model describing time-resolved approaches for both the physical aspects of tractional resistance and the physiological side of propelling force generated by muscular activity and test its validity to reproduce and forecast time trials in track cycling. Six elite track cyclists completed a special preparation and two sprint time trials in an official velodrome under continuous measurement of crank force and cadence. Fatigue-free force-velocity profiles were calculated, and their fatigue-induced changes were determined by non-linear regression analysis using a monoexponential equation at a constant slope. Model parameters were calibrated based on pre-exercise performance testing and the first of the two time-trials and then used to predict the performance of the second sprint. Measured values for power output and cycling velocity were compared to the modelled data. The modelled results were highly correlated to the measured values (R2>0.99) without any difference between runs (p>0.05; d<0.1). Our mathematical model can accurately describe sprint track cycling time trial performance. It is simple enough to be used in practice yet sufficiently accurate to predict highly dynamic maximal sprint performances. It can be employed for the evaluation of completed runs, to forecast expected results with different setups, and to study various contributing factors and quantify their effect on sprint cycling performance.

Abstract:

The purpose of this study was to describe the physiological and aerodynamic characteristics and the preparation for a successful attempt to break the 1-h cycling world record. An elite professional road cyclist (30 yr, 188 cm, 81 kg) performed an incremental laboratory test to assess maximal power output (W˙max) and power output (W˙OBLA), estimated speed ( V OBLA), and heart rate (HROBLA) at the onset of blood lactate accumulation (OBLA). He also completed an incremental velodrome (cycling track) test (VT1), during which V OBLAVT1 and HROBLAVT1 were measured and W˙OBLAVT1 was estimated. W˙maxwas 572 W, W˙OBLA 505 W, V OBLA52.88 km/h, and HROBLA 183 beats/min. V OBLAVT1, HROBLAVT1, andW˙OBLAVT1 were 52.7 km/h, 180 beats/min, and 500.6 W, respectively. Drag coefficient and shape coefficient, measured in a wind tunnel, were 0.244 and 0.65 m2, respectively. The cyclist set a world record of 53,040 m, with an estimated average power output of 509.5 W. Based on direct laboratory data of the power vs. oxygen uptake relationship for this cyclist, this is slightly higher than the 497.25 W corresponding to his oxygen uptake at OBLA (5.65 l/min). In conclusion, 1) the 1-h cycling world record is the result of the interaction between physiological and aerodynamic characteristics; and 2) performance in this event can be predicted using mathematical models that integrate the principal performance-determining variables.

Hubungan frekuensi langkah dan panjang tungkai secara bersama sama dengan hasil lari 60 meter dinyatakan dalam persamaan regresi Y = 7,5 + 0,20 X₁ + 0,65 X₂ dengan koefisien korelasi = 0,915. Dalam proses uji keberartian koefisien korelasi tersebut didapati Fhitung= 70,29 > Ftabel= 3,35 yang menunjukkan bahwa hipotesis nihil (Ho) ditolak dan hipotesis alternatif (H1) diterima. Maka didapat kesimpulan bahwa terdapat hubungan yang signifikan antara frekuensi langkah dan panjang tungkai secara bersama-sama dengan hasil lari 60 meter mahasiswa fakultas ilmu olahraga 2018. Kata Kunci: Frekuensi Langkah, Panjang Tungkai, Lari 60 Meter ABSTRACT The purpose of this study was to determine the relationship between step frequency and 60 meter running results, the relationship between leg length and 60 meter running results, and the relationship between step frequency and leg length with 60 meter run results for the 2018 Faculty of Sport Sciences Students. This research was conducted at East Jakarta Velodrome Athletic Stadium. The method used is descriptive quantitative by using correlation studies. The sample used amounted to 30 people, with a sampling technique that is purposive sampling from the existing population of 2018 Faculty of Sport Sciences Students. The relationship of leg length to the 60 meter running result is expressed in the regression equation Y = 43.29 + 0.13 X₁, with the correlation coefficient y ry〗 _1 = 0.134. In the process of testing the significance of the correlation coefficient found t = 0.715 <t table = 1.701 thus the correlation coefficient is 0.134 is not significant. The relationship of leg muscle explosive power to the 60 meter running results is expressed in the regression equation Y = 18.34 + 0.63 X2, with a correlation coefficient y ry〗 _2 = 0.633. In the process of testing the significance of the correlation coefficient found tcount = 4.328> ttable = 1.701 thus the correlation coefficient is 0.633 significant. The relationship between stride frequency and leg length together with the 60 meter run result is expressed in the regression equation Y = 7.5 + 0.20 X₁ + 0.65 X₂ with a correlation coefficient y ry〗 _ (1-2) = 0.915. In the process of testing the significance of the correlation coefficient found Fcount = 70.29> Ftable = 3.35 which indicates that the null hypothesis (Ho) is rejected and the alternative hypothesis (H1) is accepted. Then it can be concluded that there is a significant relationship between the frequency of steps and leg length together with the 60 meter running results of the 2018 faculty of sports students. Keywords: Step Frequency, Leg Length, Running 60 Meters

Abstract:

Purpose The Olympic Games is the largest sporting mega event of its type, with deep cultural and historical roots. The event is short lived compared to the lifespan of the infrastructure required in host cities. The purpose of this paper is to examine models of adaptability in Olympic construction, using case studies in previous Olympic host cities of the Summer Olympic Games (Rome 1960, London 2012), to assess the impact of adaptability on future legacy. Design/methodology/approach A mixed methods approach (archival research, direct observation), was used in two case studies: Rome (Palazzetto dello Sport, Palazzo dello Sport), and London (London Olympic Velodrome, London Aquatics Centre). The case studies examined how adaptability was used in design to secure legacy. Findings In the selected case studies (Rome 1960, London 2012), adaptability has had a positive impact on the post-Games use of venues, all four of which remain in use today. However, there are multiple factors that contribute to post-Games legacy, and further research is necessary. Research limitations/implications Whilst some positive results were observed in this study, more research is necessary across a broader spectrum of sites and venues to make conclusive recommendations for architects designing for Mega Sporting events. Social implications The significance of this study to architectural practice, academia, and society is its potential to benefit future Olympic Games, International Olympic Committee policy, and be extended to other Mega Sporting events. Originality/value The originality of this research lies within its analysis of Olympic infrastructures and sustainability, of which there is a current lack of comparative studies in academic research.

Abstract:

The individual pursuit is a 4-km cycling time trial performed on a velodrome. Parathletes with transtibial amputation (TTA) have lost physiological systems, but this may be offset by the reduced aerodynamic drag of the prosthesis. This research was performed to understand the effect of a unilateral TTA on Olympic 4-km pursuit performance. A forward-integration model of pursuit performance explored the interplay between power loss and aerodynamic gains in parathletes with TTA. The model is calibrated to a 4-km pursuit time of 4:10.5 (baseline), then adjusted to account for a TTA. Conditions simulated were based on typical pedal asymmetry in TTA (AMP), if foot stiffness were decreased (FLEX), if pedaling asymmetries were minimized (ASYM), if the prosthesis were aerodynamically optimized (AERO), if the prosthesis had a cosmetic cover (CC), and if all variables were optimized (OPT). A random Monte Carlo analysis was performed to understand model precision. Four-kilometer pursuit performances predicted by the model were 4:10.5, 4:20.4, 4:27.7, 4:09.2, 4:19.4, 4:27.9, and 4:08.2 for the baseline, AMP, FLEX, ASYM, AERO, CC, and OPT models, respectively. Model precision was ±3.7 s. While the modeled time decreased for ASYM and OPT modeled conditions, the time reduction fell within model precision and therefore was not significant. Practical application of these results suggests that parathletes with a TTA could improve performance by minimizing pedaling asymmetry and/or optimizing aerodynamic design, but, at best, they will have performance similar to that of intact cyclists. In conclusion, parathletes with TTA do not have a net advantage in the individual pursuit.

Abstract:

The present case study analyzed the pacing in a self-paced world record attempt during a 24 h track cycling event by the current world record holder. The cyclist completed 3767 laps on a 250 m long cycling track and covered a total distance of 941.873 km, breaking the existing world record by 37.99 km. The average cycling speed was 39.2 ± 1.9 km/h (range 35.5–42.8 km/h) and the power output measured was 214.5 ± 23.7 W (range 190.0–266.0 W) during the 24 h of cycling. We found a positive pacing result with negative correlations between cycling speed (r = −0.73, p < 0.001), power output (r = −0.66, p < 0.001), and laps per hour (r = −0.73, p < 0.001) and the covered distance. During the 24 h, we could identify four different phases: the first phase lasting from the start till the fourth hour with a relatively stable speed; the second phase from the fourth till the ninth hour, characterized by the largest decrease in cycling speed; the third phase from the ninth hour till the 22nd hour, showing relatively small changes in cycling speed; and the last phase from the 22nd hour till the end, presenting a final end spurt. The performance in the 24 h track cycling was 45.577 km better than in the 24 h road cycling, where the same athlete cycled slower but with higher power output. In summary, the current world-best ultracyclist covered more kilometers with less power output during the world record 24 h track cycling than during his world record 24 h road cycling. This was most probably due to the more favorable environmental conditions in the velodrome, which has no wind and stable temperatures.

Abstract:

We tested the hypothesis that presleep consumption of α-lactalbumin (LA), a fraction of whey with a high abundance of tryptophan, would improve indices of sleep quality and time-trial (TT) performance in cyclists relative to an isonitrogenous collagen peptide (CP) supplement lacking tryptophan. Using randomized, double-blind, crossover designs, cyclists consumed either 40 g of LA or CP 2 hr prior to sleep. In Study 1, six elite male endurance track cyclists (age 23 ± 6 years, 70.2 ± 4.4 ml·kg−1·min−1) consumed a supplement for three consecutive evenings before each 4-km TT on a velodrome track, whereas in Study 2, six well-trained cyclists (one female; age 24 ± 5 years, 66.9 ± 8.3 ml·kg−1·min−1) consumed a supplement the evening before each 4-km TT on a stationary cycle ergometer. Indices of sleep quality were assessed with wrist-based actigraphy. There were no differences between the CP and LA supplements in terms of total time in bed, total sleep time, or sleep efficiency in Study 1 (LA: 568 ± 71 min, 503 ± 67 min, 88.3% ± 3.4%; CP: 546 ± 30 min, 479 ± 35 min, 87.8% ± 3.1%; p = .41, p = .32, p = .74, respectively) or Study 2 (LA: 519 ± 90 min, 450 ± 78 min, 87.2% ± 7.6%; CP: 536 ± 62 min, 467 ± 57 min, 87.3% ± 6.4%; p = .43, p = .44, p = .97, respectively). Similarly, time to complete the 4-km TT was unaffected by supplementation in Study 1 (LA: 274.9 ± 7.6 s; CP: 275.5 ± 7.2 s; p = .62) and Study 2 (LA: 344.3 ± 22.3 s; CP: 343.3 ± 23.0 s; p = .50). Thus, relative to CP, consuming LA 2 hr prior to sleep over 1–3 days did not improve actigraphy-based indices of sleep quality or 4-km TT performance in cyclists.

Abstract:

AbstractThe 1972 dome to cover the Anoeta Velodrome is the product of the experiences up to that date of the architects Emilio Pérez Piñero and Félix Candela, specialists, respectively, in the design of deployable reticular structures and thin concrete shells using hyperbolic paraboloids. It is a very relevant project in the careers of both architects, as the Anoeta dome was Pérez Piñero’s last project, and also the last of the domes in which Candela participated since 1965. Pérez Piñero’s death in 1972 marked the end of a phase in Candela’s life. This paper describes the virtual reconstruction of a variation of the project and analyses its geometry, based on the subdivision of the sphere into polygons onto which hyperbolic paraboloids were then inserted. New documentation is provided which offers context for the evolution of Candela’s work, linking this project to his previous major work: the Palacio de los Deportes built for the 1968 Mexico Olympics.

Abstract:

Velodrome cycling is a sport that requires cycling on an inclined surface, and this may increase chances of injury in players. The purpose of this study was to find out the injury pattern in form of injured part, injury time, severity, type and relation with gender, level of participation and training characteristics among velodrome cycling players. Injury pattern from the last 2 years was studied in 85 velodrome cycling players aging between 15-25 years from Punjab using a scheduled interview method. The study included players who were practicing cycling at least 3 times per week for more than 2 years. The mean age of the study participants was 19.39 years (range 15-25). According to the results of this study, 48 out of 85 cyclists had sustained 75 injuries in the last 2 years, in which 52% (39) injuries were due to fall, 66.67% were traumatic injuries and 84% occurred during training time. The most commonly injured parts were shoulder and knee. For the shoulder, the clavicle was the most frequently fractured bone (11 cases) among the 85 cyclists. The severity of injuries calculated according to Ekstrand’s 3-point scale based on absence from the sports activity depicted most injuries as severe (39.58%) followed by mild (33.33%) and moderate (27.08%). It can be concluded that females were injured more as compared to male velodrome cyclists. The most common injured parts were shoulder in upper limb and knee in lower limb.

Abstract:

There are many variations to the competition that takes place in Olympic track cycling. Hence, a bicycle simulator will bring a lot of benefits to the coaches and the athletes in a practical training. It is extremely low cost compared to a real Velodrome track which is required long construction time due to the unique geometry and size. In this project, a 6-degree-of-freedom (6-DOF) motion platform is designed and developed to simulate the Velodrome track cycling. The parallel manipulator was chosen to control the moving platform because of higher accuracy and greater weight to strength ratio compare to serial manipulator. The 6-DOF platform is controlled by linear actuators and micro-controller. An optical encoder was installed for closed-loop position feedback control. An inverse kinematics model was developed to obtain the movement of the platform, and it was validated with its CAD model. Besides, a design feasibility program was developed to calculate the optimum design dimension of the motion platform. All the positions (3-axes) and orientations (3-rotational axes) data are tracked for analysis purpose. A lab-scale prototype was successfully built for the analysis and validation purpose. A standard Velodrome track dimensions was chosen to be simulated. On the other hand, a gyro accelerometer was installed at the platform to acquire the actual motion of the platform. The data will be used to validate the control algorithms and accuracy of the motion platform. The experiment was conducted and the results are analyzed for further development.
