Fastening of cargo on the car. Calculation of load shift, elongation and forces in elastic elements of fasteners. Describe the parameters of the load and the physical and geometric parameters of the load fastening; give the results of the calculation of the longitudinal forces perceived by the elements of the load fastening. The article uses the basic law of dynamics in relative motion for the non-ideal connection known from theoretical mechanics. The results of the calculation of the longitudinal forces perceived by the load fastening elements, which allowed determining the load shifts along the car, elongation and forces in the flexible fastening elements are presented. Example calculation contributes to the practical application of a new method of calculating the elements of fastening on the car in the development of schemes of placement and fastening of goods of arbitrary geometry. The results of calculations revealed that the accepted value of the coefficient of longitudinal dynamics of the car corresponds to the shunting collision of the car on the hump yard in the marshalling yards.

Abstract:
Cargo securing on a railway platform, elastic and retention fasteners, longitudinal transport force of inertia, forces in elastic fastenings. Purpose: The paper presents the calculation of the longitudinal transport force of inertia; determines the longitudinal force perceived by the elastic elements of the cargo securing; determines the reactions of retention bars depending on the number of bars and fasteners (nail); calculates the sum of all holding forces; calculates the forces in the elastic fasteners when exposed to longitudinal forces. Research methods: To determine the forces in the cargo securing devices, existing calculation methods are used. Moreover, the formulas of these techniques are presented in a form convenient for calculation. Main results: The paper proves that according to the existing method, the force in all elastic cargo fasteners under the influence of longitudinal forces has the same value, regardless of the different arrangement of the geometric parameters of the fasteners in space. The forces in them are more than 1.6 times higher than the permissible values. The calculations of forces in the elastic fasteners, which are performed by the specified method, are given. The results of the comparative analysis showed that the forces in all wire fasteners, in contrast to the existing calculation method, have different values. However, the strength of the second pair of wire fasteners of both one and the other direction is not ensured - the force in them more than two times exceeds the permissible value (61/24.8≈2.5), which will result in their destruction during the cargo transportation. Conclusions and their significance for the industry: Existing calculation methods do not provide guarantee strength of cargo fasteners. In the future, to calculate the fastening of cargo by shippers in the railway industry, a new calculation procedure should be applied for the allocation and fastening of cargo on the car.

Abstract:
Inaccuracy of the existing methodology for calculating cargo fastening. Cargo fastening by flexible and retention elements. The paper should define the “shearing” force across the car as the sum of the transverse transport inertia and wind load, taking into account the safety factor from tipping over; determine the transverse force perceived by the means of securing the load, taking into account the reaction of the retention bars of only one direction; calculate the forces in the elastic fasteners when exposed to shearing forces, taking into account the geometry of the fasteners according to existing methods. The research methods are based on the basic law of dynamics for the relative motion of a material point, where the transverse and vertical transferring inertia forces are formally assigned to external forces. The paper proves that according to the existing methodology, the force in all elastic cargo fasteners under the influence of transverse forces has the same value, regardless of the different arrangement of the geometric parameters of the fasteners in space. This is not true. The calculations of forces in the elastic fastening elements according to Appendix 8 of the existing methodology are given. Under the influence of transverse forces, the strength of the first and second pairs of elastic fasteners, both one and the other direction, are not provided by the method of Appendix 8 - the forces in the fasteners are greater than the permissible one (24.8 kN). Existing calculation methods do not ensure the strength of the cargo fastening elements.

Abstract:
AbstractEnsuring transport safety is one of the key areas of transport companies’ operations. Management and organization processes not only in the intermodal transport are associated with decision-making in regard to adequate load securing, which is exposed to the inertia forces resulting from the movement of transport means. Regardless, the responsibility of individual entities in the process and the applicable insurance, the basic aspect to ensure transport safety is the correct securing of the cargo. In the article, the authors present elements of calculation models for different methods of securing cargo. Calculations were performed for the selected type of load on the specific semi-trailer meeting the requirements of the XL Code adapted for intermodal transport. The analysis of safety management in transport in the aspect of decision-making about the method of securing the cargo was also made.

Abstract:
During the transportation of goods, damage and destruction of the transported cargo constitute a very large part of the damage. The most common direct cause of damage is an improper arrangement and securing of the transported load. An improperly secured load may pose a threat to the transporters and bystanders. Incorrectly secured loads can fall from the vehicle, obstruct movement, and cause injury or death. In addition, improperly secured loads can cause injury or death in heavy braking or a collision. The way the load is distributed and secured on the vehicle can negatively affect driving behaviour, making it difficult to control the vehicle. This article presents the conditions related to the transport of loads in road transport, describes both the forces that act on the load during the journey of a vehicle and the most important techniques for securing loads in road transport.

Abstract:
At the site of cargo package binding in cargo spacecraft, the binding belt tension is loaded with a ratchet device. It is determined by experience of operators, therefore it’s difficult to quantify the force and the reliability of the binding belt is low. Based on the dimension analysis method, a semi-quantitative model was established between the binding belt tension and the ratchet force of the fastening device. The motion of the binding process was carefully observed and analyzed based on Analysis of Therbligs. On this basis, the standard packing process is developed, which improves the repeatability of loading and packing pre loading. A loading test platform for cargo loading is built with small tension sensor and tension tester, and a large number of tension data and ratchet force data are obtained. Based on the least-squares linear data fitting, four coupling models for the four binding belts were established. The coupling model verification experiments show that the calculated values are in good agreement with the measured values, and the errors are mostly lower than 5%. The model can be applied to the quantification of the binding belt tension.

Abstract:
This paper dwells upon securing solid cargo on a railcar. Transverse cargo shift and forces of elastic securing devices. The authors sought to calculate the shearing force acting on the elastic securing elements and retention bars; the retentive forces that prevent cargo from shifting across the car (the transverse shift); the transverse cargo shift; the force of elastic securing elements as exposed to transverse forces. This study relies on the second law as applicable to relative motion for a frictional constraint, as known in theoretical mechanics. The paper presents the calculated shearing and retentive forces. The authors calculated the equivalent stiffness of elastic securing elements. They thus computed the transverse shift (displacement) of cargo and the elongation of each elastic element that secures the cargo. They also found the forces of elastic securing elements as exposed to transverse forces. It was thus discovered that the forces of the second securing pair were more than double the acceptable limit, which would cause that pair to break during transport. To make the second elastic pair stronger, one might double the number of retention-bar fasteners so that the forces of the second fastening pair wouldn’t exceed the limits. An example of calculation is useful in developing a new methodology for calculating the elements of cargo securing on a car. The calculation results proved that to ensure guaranteed safety and reliability of the transportation process, it is necessary to either increase the number of securing elements of the retention bar, or increase the number of elastic securing elements with subsequent recalculation of forces in all elastic securing elements.

Abstract:
The aim of this thesis was to develop a new turnbuckle for fastening containers on cargo ships. The design was supposed to indicate whether the turnbuckle could be re-used, i.e. it hadn't plastically deformed. This indication could reduce the risk of a turnbuckle breaking during transport, since turnbuckles that have been exposed to a load above their safe working load would indicate this. \newline In total 25 different concepts were developed and put through two different elimination matrices which were evaluated against a requirement specification. The final design had calculated stress of 630 MPa at breaking load and 472 MPa proof load, the loads are defined by Germanischer Lloyd. A concept for measurement of the deformation of the turnbuckle was developed, however it is in need of further development and testing before it can be implemented. A suggestion of manufacturing method, material and surface treatment has been given, but prototype testing is required to verify the design and ensure adequate corrosion protection.

Abstract:
The objection of this dissertation is to examine effects of stowed cargo on safety driving of a vehicle. Based on general experience of weighing trucks and monitoring of cargo fixture, my attempt was to summarize related legislative conditions of the operation of trucks in terms of payload, weighing and stowing of cargo. In the first part I worked on consistent methodology of stowing and fastening of cargo on trucks. I've included various methods of loading cargo and different ways of fastening and their calculations. The main body of the second part is a practical methodology of inspectional weighing of trucks on the road. In this section I took into account the current method and procedure of inspectional weighing and measuring of trucks. During my trial weighing of different types of trucks I proved that the key factor for safe seating and lashing of load on a vehicle is determining center of gravity of the vehicle. I solve this problem in detail in the last part of my work.

Abstract The integration of custom risk management and transportation technology is essential for current developments of international transportation. Nonetheless, the clear version for the systems reengineering and design in Taiwan is still deficient. So, this study aims to explore the backgrounds and experiences for the simplicity of custom regulations out of some developed countries, and thus, plot an improved and reasonable system for local custom regulations through system technological, risk and economics assessments. This research project would be undergone through a teamwork design coordinating those involving the developed issue, including the public agents and industries, to improve its feasibility and practices as well as create the communicating channel for the cross-field issue. In this project, we identified five information features as the functional needs of container tracking systems, and survey 17 customs officers to get varied needs, With the excellence of providing thorough abnormal-identification and responsive functions, AVL was considered as the most suitable technology for developing container tracking systems. We took it as an initial system. Thereby, Failure Mode Effect Analysis (FMEA) is applied to identify and establish the model of risk resulting from the operations of the novel technologies. Development and utilization of information systems are the core mission of ITS. The quality of information reliability is highly associated with the success of the project and satisfactions of the users. But practices on analyzing and justifying information risk were rarely seen. In our case study, we found risk management technique could pertinently applied to define, identify, measure, assess and control the losses resulting from information failures. The FMEA approach could be used to well define tracking information risk and locate the major failures of information technologies. In addition, based on the risk triangle principle, information systems and risk mitigation measures can be rationally justified to ensure the user acceptance and economics. Finally, with the explicit, logic process of risk management, the customized information systems were found to be well documented for project persuasions.
