Study on dynamic characteristics of train collision based on Multibody Dynamics

Abstract

In order to study dynamic response of train collision based on the theory of multi-body dynamics, a multi-body dynamic model of two trains of high-speed trains was established by using MATLAB software. The numerical method is used to simulate the collision process of 6 marshalling trains. This paper studies the influence of the configuration of energy absorber, such as buffer, crushing tube and anti-creeper at different speeds of trains and strength gradient of crushing tube and anti-creeper on impact characteristics of train connected. The results show that the rational allocation of energy absorption components can effectively control the average energy absorption of the train.
