Dynamic Simulation of Tank Car Derailment and Structure Optimization Based on Solidworks, ADAMS, and ANSYS

摘要

This paper establishes a three-dimensional model of tank car derailment and collision to analyze gross motions and forces in this process with the GQ70 tank car as the research object. To simplify the complexity of the model, it is implemented in ADAMS, thus the author summarizes each of the three most dangerous conditions of tank car and the corresponding force spectrum files. Based on the above results, this collision is examined using dynamic, nonlinear finite element analysis. The results indicate that it is essential for optimization design of tank car, including optimization of the tank car itself and coupler. This paper aims to optimize tank car to be capable of surviving impact speed as twice as now. The contents of this paper provide the ideas of optimization design and the research results lay a solid foundation for railway vehicle safety management and vehicle maintenance, being of theoretical significance and practical value.
