Abstract:
Abstract. Aim. Hydraulic rotary vane motors rely on the principle of torque maintained at a nominal pressure. In this case, the most important parameter of the torque is its nonuniformity. The problem of determining nonuniform torque in hydraulic motors having ten and twelve vanes is investigated with the aim of ensuring the maximum stability of this parameter.Method. Braking torque occurs on the vanes of hydraulic rotary vane motors due to the pressure of the working fluid on the stator; the theoretical expression for torque does not take the braking effect of the vanes into account. Therefore, an expression is compiled for the braking torque of the vanes with a type of stator curve that provides constant acceleration of the vane relative to the rotor.Results. Plots of changes in braking torques were constructed for 10- and 12-vane motors. Ratios of the minimum and maximum braking torques equal to 0.33 and 0.5 for motors with ten and twelve vanes, respectively, were obtained.Conclusion. The torque nonuniformity coefficients for hydraulic motors for the given parameters of d =11,6% and d = 8,8% for motors having ten and twelve vanes, respectively, were obtained. The results of the analysis of the obtained parameters indicate a slight increase in the nonuniformity of torque in a ten-vane motor. In this case, a decrease in the number of vanes leads to an increase in the mechanical efficiency of the hydraulic machine.

Abstract:
Dynamic brake characteristics of disc brake during emergency braking of the kilometer deep coal mine hoist were investigated in the present study. The theoretical model of dynamic brake torque of disc brake during emergency braking was given to explore dynamic brake torque properties of disc brake. The three-dimensional thermo-mechanical coupled finite element model of brake disc–brake shoe was established to explore thermo-mechanical characteristics of disc brake during emergency braking. Effects of effective mass, hoisting acceleration and deceleration, and maximum hoisting speed on dynamic brake torques, equivalent von Mises stress, and temperature fields of disc brake during emergency braking were presented. The results show that the evolutions of brake torque, equivalent stress, and temperature of disc brake present fluctuating characteristics. The dynamic brake torque shows the largest change amplitude during emergency braking in the hoisting stage of constant speed. The largest equivalent stress and temperature are both located near the third brake shoe along the rotational direction at each side. An increase in effective mass causes overall decreases in the peak values of brake torque, equivalent stress, and temperature during emergency braking. Increases in hoisting acceleration/deceleration and maximum hoisting speed cause the increases in the maximum equivalent stress and temperature during emergency braking as compared to the slight decrease in the maximum brake torque.

Abstract:
In order to improve the inspection efficiency and accuracy of the braking capacity of the elevator brake being used, a novel method for analyzing the full-loaded braking performance by using the unloaded braking performance is proposed, and a set of methods for measuring the braking torque is designed. Based on the analysis of the key factors that affect the mechanical performance of the elevator brake, the calculation model of the braking torque in the process of the emergency braking with the traction ratio of 2 : 1 is established, and the relationship between the braking torque and acceleration under different working conditions is analyzed. It is shown that, for the model assumed, the emergency braking torque is 1.56 times that of the static braking torque under 1.25 times the rated load. The braking torque increases linearly with the increase of braking acceleration. An elevator model being used is tested and calculated. The experimental results show that the braking acceleration measured by the experiment is 11.95% less than the theoretical value. And the analysis shows that, comparing with the traditional test method, the braking torque test method designed in this paper is more accurate and safe.

Abstract:
The electro-hydraulic composite braking system of a pure electric vehicle can select different braking modes according to braking conditions. However, the differences in dynamic response characteristics between the motor braking system (MBS) and hydraulic braking system (HBS) cause total braking torque to fluctuate significantly during mode switching, resulting in jerking of the vehicle and affecting ride comfort. In this paper, torque coordination control during mode switching is studied for a four-wheel-drive pure electric vehicle with a dual motor. After the dynamic analysis of braking, a braking force distribution control strategy is developed based on the I-curve, and the boundary conditions of mode switching are determined. A novel combined pressure control algorithm, which contains a PID (proportional-integral-derivative) and fuzzy controller, is used to control the brake pressure of each wheel cylinder, to realize precise control of the hydraulic brake torque. Then, a novel torque coordination control strategy is proposed based on brake pedal stroke and its change rate, to modify the target hydraulic braking torque and reflect the driver’s braking intention. Meanwhile, motor braking torque is used to compensate for the insufficient braking torque caused by HBS, so as to realize a smooth transition between the braking modes. Simulation results show that the proposed coordination control strategy can effectively reduce torque fluctuation and vehicle jerk during mode switching.

Abstract:
The dynamic response of a high-speed multiple-railcar train experiencing deceleration under braking condition over a straight track is investigated using the moving element method. Possible sliding of train wheels over the rails is accounted for. The train is assumed to comprise a locomotive as the leading railcar and several passenger railcars connected to each other through train couplers. Each railcar is modeled as a 15-DOF system of interconnected car body, two bogies and four wheels. The rail is modeled as an Euler–Bernoulli beam resting on a two-parameter elastic damped foundation. The train and rails are coupled through normal and tangential wheel–rail contact forces. The effects of various parameters, such as braking torque, coupler stiffness, coupler gap, wheel load, wheel–rail contact condition, initial train speed and partial failure in braking mechanism on the dynamic response of the train subject to braking are investigated. It is found that there is significant interaction between neighboring railcars when the braking torque is applied between the optimal and critical torques. The former is the torque that would result in the smallest braking distance with no occurrence of wheel sliding and the latter is the smallest torque to cause wheel sliding in all four wheels.

Abstract:
Electric vehicles are spreading in automotive industry pushed by the need of reducing greenhouse gas. However, the use of multiple electric motors, i.e., one per wheel, allows to redefine the vehicle powertrain layout with great benefits on vehicle dynamics. Electric motors braking torque is in general not enough to produce high decelerations. Hydraulic friction brakes are still necessary for safety reasons and to avoid oversized motors. This paper presents a control strategy for distributed electric motors (EM), one per wheel, to maximize the regenerative braking. The controller handles cooperative braking among EMs and hydraulic brakes, which are still necessary to guarantee top braking performance of the car. The proposed algorithm considers the driver requested braking torque as well as the required yaw moment by stability control system. Motor efficiency map and wheel normal load are considered to optimally distribute the torques. With respect to conventional distribution strategies, the presented algorithm improves performance, maximizing the regenerative braking power.

Abstract:
The coordinated control of a blended braking system is always a difficult task. In particular, blended braking control becomes more challenging when the braking actuator has an input time-delay and some states of the braking system cannot be measured. In order to improve the tracking performance, a coordinated control system was designed based on the input time-delay and state observation for a blended braking system comprising a motor braking system and friction braking system. The coordinated control consists of three parts: Sliding mode control, a multi-input single-output observer, and time-delay estimation-based Smith Predictor control. The sliding mode control is used to calculate the total command braking torque according to the desired braking performance and vehicle states. The multi-input single-output observer is used to simultaneously estimate the input time-delay and output braking torque of the friction braking system. With time-delay estimation-based Smith Predictor control, the friction braking system is able to effectively track the command braking torque of the friction braking system. The tracking of command braking torque is realized through the coordinated control of the motor braking system and friction braking system. In order to validate the effectiveness of the proposed approach, numerical simulations on a quarter-vehicle braking model were performed.

Abstract:
This paper presents a new approach to the design, testing and analysis of a magnetorheological brake which uses a multi-path magnetic circuit to satisfy the braking demand of vehicles. In contrast with a general braking system, an automotive brake exhibits an outstanding performance for high torques and long reaction times. We use a proposed power-law model and finite element analysis to obtain the magnetorheological braking performance for a high shear rate and a high-intensity magnetic field. Finite element analysis with different structures is adopted to determine the parameters of the magnetorheological braking and the layout of the magnetic circuits. An integrated prototype is also fabricated and tested. The test results show that the brake torque is relatively high, and the torque can be accurately controlled by the input current. The reaction time is less than 100 ms. We also analyse the experimental results and use these as the basis for fabricating a full-sized prototype. The full-sized prototype generally exhibits a high torque capacity and a fast dynamic response, thereby validating the feasible application of magnetorheological fluids in automotive braking.

Abstract:
In this article, a new high-torque retarder combining the effects of magnetorheological fluid and eddy current is researched. The new retarder provides a part of the braking torque generated by the shear stress of the magnetorheological fluid and an additional braking torque generated by the effect of the eddy current on the rotors. This operating concept is realized by a common magnetic excitation circuit generated by a new structure with several separated coils. The configurations and design details of the new retarder, including the structure, material selection, and magnetic circuit, are discussed. The mathematical models of braking torque caused by the magnetorheological fluid and eddy current are also derived. Then, a finite element analysis is performed to verify the magnetic field design of the new retarder. Finally, a prototype is fabricated, and the relevant parameters are tested. The experimental result shows that the new retarder provides not only a stable braking torque at low speed but also a great increment of braking torque varied with rotation speed, which effectively improves the total braking torque compared with conventional magnetorheological retarders.

Abstract:
Dither control is a method of introducing high frequency control efforts into a system to suppress a lower frequency disturbance. Dither control is an effective means of suppressing automotive brake squeal. Brake squeal is a problem that has plagued the automotive industry for years. In fact many makers of materials for brake pads spend up to 50% of their engineering budgets on noise, vibration and harshness issues. A normal dither signal may be introduced to an automotive braking system by placing a piezoceramic stack actuator in the piston of a floating caliper brake. Many theoretical models indicate a reduction in the braking torque due to the dither signal. Under the assumption of Hertzian contact stiffness the loss in braking torque is due to lowering of the average normal force. There are also theories that the dither signal eliminates the stick-slip oscillation causing an effective decrease in the friction force. Yet another theory indicates that the effective contact area is reduced, lowering the mean coefficient of friction. It is not apparent whether any of these models accurately portrays the interaction of the brake pads and rotor.

Abstract:
The limitations of current simulation packages in addressing the true longitudinal behaviour of railway bogie dynamics during braking/traction has prompted the development of a Rail Bogie Dynamics (RBD) program in this thesis. The RBD program offers novel features for the calculation of the speed profile as a function of the brake torque as well as explicitly determining wheelset angular velocity. With such capability, the speed profile is no longer treated as an input calculated as a priori as required by most of the current simulation systems. The RBD program has been developed using a formulation that includes the wheelset pitch degree of freedom explicitly with a coordinate reference system that is fixed in space and time. The formulation has made the simulation of the bogie dynamics during braking/traction possible in a natural way using the brake/traction torque as the input and the resulting speed profile as the output without any need for working out the speed profile as a priori. Consequently, severe dynamics during braking such as the wheelset skid and the onset of wheel climb derailment can be modelled and critical parameters investigated using the RBD program. The RBD program has been validated, where possible, through a series of simulations using a commercial software package (VAMPIRE). For cases which cannot be simulated by VAMPIRE such as the wheelset skid, a novel experimental program has been designed and commissioned in the Heavy Testing Laboratory of the Central Queensland University as reported in this thesis. One of the possible applications of the RBD program in examining the effect of asymmetric brake shoe force in bogies equipped with one-side push brake shoe arrangement is illustrated in this thesis. It is believed that the model and RBD program will have significant benefit in understanding the true longitudinal behaviour of wagons in suburban passenger trains that operate under braking/ traction torques for most of their travel. Similar studies will also be useful to freight train wagon dynamics during entry and exit of speed restriction zones and tight curves.

Abstract:
This master thesis report has studied several methods to improve the energy consumption of an electric vehicle equipped with two permanent magnet synchronous motors. Two driving torque distribution maps are developed based on efficiency map and load transfer, respectively. The drive torque distribution map based on the efficiency map shows up to 8.94% energy saving. Two regenerative braking strategies are designed and compared. Both strategies have pure regenerative brake at low decelerations and it is controlled by a modified acceleration pedal map. Strategy 1 does not add more regenerative braking when the brake pedal is pressed thus it is simpler while strategy 2 can blend in more motor torque. Rear axle steering is also studied in terms of contribution to energy consumption and an LQR controller is developed to control the vehicle with rear axle steering.
Denna rapport avhandlar ett examensarbete där flera metoder har studerats för att förbättra energikonsumptionen för ett elektriskt fordon med två permanentmagnetsynkrona motorer. Två fördelningskartor för drivande moment är framtagna baserat på effektivitetskartor och lastöverföring. Fördelningskartorna för drivande moment som är baserat på effektivitet visar upp till 8,94% energiminskning. Två olika regenerativa bromsstrategier är framtagna och jämförda. Båda strategierna har ren regeneration vid låga decelerationer och är reglerat genom modifierat gaspedalsmappning. Strategi 1 ger inte mer regeneration när bromspedalen trycks ned och är då enklare medans strategi 2 kan blanda in mer vridmoment från elmotorn. Bakaxelstyrning är också studerat i termer av dess bidrag till energikonsumption samt en LQR regulator är utvecklad för reglering av fordonets bakaxelstyrning.

The dissertation for obtaining a scientific degree of the Candidate of technical sciences on a specialty 05.05.05 "Lifting and transportation machinery". – Ternopil Ivan Puluj National Technical University, Ternopil, 2021. In the dissertation, on the basis of the set of generalized scientific results, the new actual problem of increasing the technological efficiency of screw transport mechanisms operation process is solved due to design improvement and substantiation of parameters of the inertial planetary safety clutch, which is produced on the basis of the biplanetary inertial mechanism with a mobile reactive link. On the basis of the conducted theoretical and experimental research the following has been developed: analytical dependences which allow to analyse the displacement of the imbalance point and the mechanism in general; analytical dependences for determination of kinematic and dynamic parameters of the operation stop mode of the screw conveyor with inertial planetary safety clutch; empirical equations that characterize the change in braking torque of the stop mode and the torque transmission efficiency. Grounded on the conducted theoretical and experimental research, the optimal parameters of the inertial planetary safety clutch of the screw conveyor are substantiated. The braking safety torque of the output shaft of the screw conveyor inertial planetary safety clutch in the stop mode is formed by means of increasing the imbalance energy due to acceleration of the imbalance rotation around its axis and the drive axis of the pulse module as well as range variation of 19.6 … 29.4 N∙m, when respective gear ratio of the imbalance drive equals to 2.2. Rational functioning of the process of the screw conveyor operation in terms of providing maximum braking torque of the output shaft in case of overload of its working parts in the range from 20 N∙m to 42 N∙m, or the beginning of the stop mode of the screw conveyor, is achieved by the following parameters: input shaft speed is from 262.5 rpm to 437.5 rpm; the gear ratio of the upper imbalance drive is from 2.0 to 3.2 and the lower imbalance drive is equal to 1.0. The annual economic effect achieved by increasing the technological capabilities of the screw conveyor is UAH 12,209.7. The research results were implemented at PJSC "TerA" (Ternopil), LLC "Ukraine" (Ternopil region, Pidvolochysk district) and PP "Ukraine-Agro-2C" (Khmelnytsky region, Chemerivtsi district) in technological lines, respectively, for transportation and dough formation and for transportation of bulk products and goods.

Abstract:
This chapter presents an optimum design of synergetic control for a permanent magnet synchronous motor (PMSM) drive system. New macro-variables are proposed to improve the performance of the standard controller. The controller’s performance is compared with that of the field-oriented control scheme. The chapter also investigates the regenerative braking mode of operation in PMSM. Regenerative braking is achieved by operating the motor in torque control mode. The different algorithms are validated through experiments using a 1-hp PMSM drive system. We also provide an extensive study of the controller parameters tuning for optimal performance. The experimental results show that the proposed macro-variables improve the performance of the synergetic controller significantly. The synergetic controller is able to overcome nonlinearities in the system, such as static friction, faster than the field-oriented controller. The system also experiences fewer harmonics under the synergetic controller. The synergetic controller shows also better performance under wide signal variations. As for regenerative braking, the torque control mode of operation is shown to be suitable for harvesting energy and both techniques showed similar performance levels. The proposed synergetic control strategy will be very useful in electric vehicle (EV) applications, as it allows to improve the dynamic response and efficiency of the drive system required by the EV dynamics.

Abstract:
The paper presents the research results on the dynamic load of tractor semi-trailer on a straight road with the maximum longitudinal friction factor?xmax=0.8 at speed V0=[60, 80]km/h, being braked with 6 different braking torques. The method of structural separation of a multi-body system is used to build a 3D dynamic model of the tractor semi-trailer and the Newton-Euler equation is used to set up the system of dynamic equations of tractor semi-trailer. Matlab-simulink software is used to examine the effects of braking torque on dynamic load of the tractor semi-trailer. The results showed that, the wheel force of axle 1 is increased by 200%, but the wheel force of axle 3 is reduced about 13.3%, and the wheel force of axle 6 is reduced about 21.6%.The dynamic load factor of axle 1 is increased by 200%, but the dynamic load factor of axle 3 is reduced about 9%, and the dynamic load factor of axle 6 is reduced about 22%.

Abstract:
The anti-skid system of the automobile drive adopts the control of the engine torque and/or braking torque, which can be used to prevent the wheel from slipping on slippery roads and improve the acceleration performance, driving stability and maneuverability of the automobile. This article mainly solves how to realize the anti-skid driving of the car by controlling the throttle. For the purpose of improving automobile driving performance, its anti-skid control algorithm includes control gain adjustment and road adhesion coefficient estimation. Through various automobile tests on three low-adhesion roads, the anti-skid control algorithm is effectively proved.
