摘　　要：利用AIP创建了基于标准轮辋和轮胎的零压续跑轮胎内支撑三维参数化模型和虚拟装配体,考虑车辆速度、内支撑材料、载荷和受力等因素,通过内嵌于AIP的ANSYS技术模块创建了内支撑三维有限元模型,获得了三维应力、变形和安全系数,并根据分析结果改进了内支撑结构。对比分析改进前后内支撑三维应力,结果表明改进后的内支撑等效应力和最大主应力都小于材料屈服极限,安全系数提高,达到了预期的内支撑安全性能。Using Autodesk Inventor Professional （AIP） system, a three-dimensional parameterized model of insert and the virtual assemblage based on the standard rim and tire was established. The three- dimensional finite element analysis （FEA） of insert was performed through ANSYS technology embedded in AIP analysis types. During the FEA progress, vehicle velocity, insert material, loads and forces were defined and added on the insert. Subsequently, the three-dimensional FEA mesh was created, and stress, displacement, safety factor were obtained after finite element calculation. Finally, some modifications of insert configuration were carried out according to the analysis results. Through analysis of the new insert model, the results showed that the von-stress and the maximal principal stress were less than the yield limit of insert material, the safety factor was enhanced and the desired results was achieved, which could provide vehicle with enough safety performances.
