Simulation Study on Front Impact Safety of Medium Coach

Abstract

建立半承载式中型客车的正面碰撞有限元模型,采用lS-dynA软件进行仿真分析。结果表明,该车驾驶室变形较大、完整性较差,需对客车前部吸能结构进行优化设计。The finite element model of front impact of medium coach is built,which body is semi-integral type.Using LS-DYNA software,the front impact safety is simulated.The results indicate that the drive cab deformation is bigger and its integrality is worse,so it is necessary to optimize the front absorbing structure components to the coach drive cab.交通部西部交通科技项目(2009318000043);福建省教育厅科技项目(JA11239);厦门理工学院科技项目(JKY10023R);福建省自然科学基本项目(2012J05103
