Abstract

Abstract: Based on the national statute GB11567.2-2001, the static loading test was designed based on the strength of a prevalent rear defend device. CATIA software was used to create a 3D model of the automotive rear defend device. Through the HyperMesh and ANSYS software the strength of this device was calculated. The comparative analysis of static strength was done with different loading methods. Thus a new improved design of defend device was proposed, which has practical engineering significance for enhancing the structural design and of the protective effect of passive collision occupant safety.

Key words: vehicle engineering;rear defend device, finite element, strength analysis

摘要： 根据国家法规GB11567.2-2001，针对国内重型车辆常用后防护装置的强度设计静态加载试验，利用CATIA软件建立其后防护装置三维模型，通过专业有限元软件HyperMesh及ANSYS对该装置进行强度计算，采用不同加载方式对后防护装置的静强度对比分析,提出了新的后防护装置改进设计方案,对结构设计改进和提高被动碰撞时乘员安全保护作用具有实际工程指导意义。
