Optimal Design of Rail Support Structure for Mountain Rail Transport Vehicle

The rail transport vehicle is a solution for the transportation of heavy materials in mountainous areas. The support scheme of the rail is the key and difficult point of the design, but unified design criterion has not been established in many industries. In order to meet the requirements of the technical development of rail transport vehicles and improve the reliability of rail transport, the rail support structure needs to be optimized. This paper uses ANSYS Workbench 19.0 to analyze the strength of the rail support structure of the dual rail transport vehicle, compares the stress conditions of the three support structures, and optimizes the design of installation height of the support to ensure the safety and reliability of the support structure in practical applications. The final analysis results show that the stress of the cross-braced structure scheme is optimal, and within the range allowed by the structural design, the height of the connection point of the diagonal bracing can be increased as much as possible to increase the structural stability.
