Research On Crashworthy Passenger Safety For High-Speed Trains

The existence of high-speed trains to shorten the distance between cities, between provinces and convenient travel of people, both as a manifestation of China’s rapid economic development of China’s railway industry is a necessary requirement for sustainable development. However, every coin has two sides, in terms of providing people with high-speed trains and also on people’s lives and safety of a threat. High-speed trains in operation, the event of an accident, then the consequences is that we can not afford, so the high-speed train technology research for security aspect is particularly important. In this paper, based on research status in this field, focusing on the "crashworthiness" Design and simulation design which focuses on vehicle technology were discussed, and further analysis of the high-speed train in passenger safety protection.Firstly, research status motor vehicle passive safety technologies summarized statements, and based on the actual case of the occurrence of a higher frequency of motor vehicle collisions are classified. Subsequently, the paper briefly discusses the train collision simulation applied to the relevant knowledge and theories, such as finite element contact algorithm, the basic mechanics theory and formula equations, nonlinear characteristics, and so on, and according to the above theory, CRH5 high-speed train, for example, model, Analysis.Finally, we learn from the automotive sector crash occupant safety standards within the EMU occupant crash safety were assessed. Study the impact on the safety of the vehicle interior when the distance between the seat of the collision, and according to the assessment of the effect of the train within the seat spacing and layout to give recommendations.
