The Simulation Study for Energy-Absorbing Properties of the Railway Vehicle’s Anti-Climber with Different Vertical Offsets
暂无分享,去创建一个
Anti-climber is one of the most important passive safety devices for railway vehicles. Based on the non-linear finite element method, properties of the anti-climber with different vertical offsets are simulated by the software LS-DYNA. The force-displacement curve is mainly analyzed, and the energy absorbed by the anti-climber is also calculated in order to assess the properties. At last, an improvement method with a cross structure inside the anti-climber is designed for the offset problem and is proved effective by the simulation.
