|
摘要
以某车型的左前车门为研究对象,将多目标优化方法与正交试验设计设计方法相结合的方法应用于车门系统零部件厚度参数优化设计。利用Hyperworks软件建立车门有限元分析模型,并对其进行模态、刚度分析,然后进行模态试验和刚度试验验证分析模型的正确性;以车门板件厚度为变量对车门系统各个性能进行灵敏度分析,选取对车门性能影响较大的车门板件厚度为控制因素,应用带权重的分目标乘除法构造车门系统的综合性能评价函数,采用正交试验设计方法针对车门系统的综合性能进行参数优化设计,最终获取车门系统各个零部件厚度参数的最佳组合。
Taking the left-front door of a type of car as the study object, the method which combined multipurpose optimal method with orthogonal experimental design was applied to parameters optimization design of the thickness of the door system components. Hyperworks software was used to establish a car door finite element analytical model on which a modal and stiffness analysis was performed, and then modal test and stiffness test were proceeded to testify and analyze the correctness of the model. Sensitivity analysis was conducted on each performance of the car door system with car door plate's thickness being the variable; a car door plate thickness with comparative large influence on car door performance was selected as the controlling factor; a comprehensive performance evaluation function for car door system was constructed with the adoption of weighted sub-goals multiplying and dividing calculations; the orthogonal experimental design was applied to the parametric optimization design on car door system's comprehensive performance. Finally, the best combinations of all components' thickness parameters for car door system were got.
