Computer Simulation of Crash Process of Locomotive

摘要

In order to understand safety performance of locomotive, using explicit integral algorithm of finite element method, based on analyzing the relation between car body and bogie in DF_(8B) locomotive, considering elastic bogie and track rail, simulation model of whole DF_(8B) locomotive impacting with rigid wall face to face with velocity of 10m/s and 15m/s is established. According to the crash result, this model can simulate preferably the real crash process and provide guidance for crash safety design of locomotive.
