摘　　要：为解决某汽车减振器耦合杆支架在疲劳寿命试验中无法满足主机厂标准问题,利用ARIZ算法对减振器系统进行功能分析并建模、建立因果链提出根原因、确定冲突区域、通过IFR资源分析以及建立SLP模型,生成多个优化方案,并结合有限元仿真对支架进行寿命分析,得到产品设计最优解。在此基础上,对优化后减振器耦合杆支架进行台架疲劳寿命试验。结果表明:优化后减振器耦合杆支架的台架疲劳寿命试验数据满足主机厂要求,说明基于ARIZ和有限元方法对耦合杆支架疲劳分析具有适用性和可靠性。To solve the problem that the coupling rod brackets of the shock absorbers cannot satisfy the standard in fatigue life tests,the Ariz algorithm is used to analyze and model the shock absorbers system,to establish the causal chain and present the root cause,to determine the conflict areas and generate multiple optimization solutions after analysis of the IFR resource and SLP modeling.The optimal solutions of product design are obtained based on finite element fatigue life simulations.Then the coupling rod brackets fatigue life tests are carried out again and the test results meet the requirements.The results show that the fatigue analysis of the coupling rod brackets based on Ariz and finite element methods are viable and reliable.
