摘　　要：为了提升汽车拖钩结构强度,根据国标GB32087-2015《轻型汽车牵引装置》的要求,在HyperMesh软件中建立某车型后拖钩强度的有限元模型。首先,利用ABAQUS/Standard求解器进行拖钩强度分析,预测结构的风险区域,同时,应用CAE拓扑优化技术对其进行优化分析和改进设计,改进后的结构满足强度分析要求。最后,对改进方案的结构进行拖钩强度试验验证,结果表明改进方案满足设计要求,从而验证了拖钩强度有限元模型的准确性,为拖钩强度分析和优化设计提供依据。In order to improve the strength of car towing hook,according to national standard GB32087-2015《towing devices for light-duty vehicle》,The finite element mode was built by HyperMesh software.Firstly,the strength analysis of towing hook was carried out by the ABAQUS/Standard solver module,which can be used to predict the hazard area of structure.Meanwhile,the optimization analysis and improvement designing of towing hook structure strength were used by CAE topology optimization,the improvement program shows that the result meet the strength requirement.Finally,the strength test verification of the improvement program structure was carried out,the results showed that the improvement program meet the design requirement.Thus,the accuracy of the finite element model of the towing hook strength was verified,which provided towing hook strength analysis and optimization design.
