基于Kriging近似模型的某轿车前悬架不确定性优化OA北大核心CSCDCSTPCD
Front Suspension Uncertainty Optimization of a Car Based on Kriging Approximation Model
针对前悬架确定性优化没有考虑参数不确定性时存在的问题,提出了一种考虑不确定性因素的前悬架不确定性优化方法.应用ADAMS/Car建立了某轿车麦弗逊式前悬架模型,在ADAMS/Insight中进行了悬架设计硬点参数的灵敏度分析,针对灵敏度较大的设计硬点参数和所考虑的不确定性量,建立了车轮定位参数在车轮跳动过程中的Kriging近似模型,简化了优化过程.针对该近似模型进行了动力学分析,运用经过改进的非支配排序遗传算法(NSGA-Ⅱ)和隔代遗传算法(I…查看全部>>
For the optimization of a front suspension was almost based on certainty optimization without considering all kinds of uncertainty in the process of practical work,a uncertainty optimization method of the front suspension was proposed. Macpherson suspension model of a car was built based on ADAMS/Car. The design parameter's sensitivity was analyzed by ADAMS/insight. And then, a Kriging approximate model was established for the greater sensitivity of design p…查看全部>>
