以摩托车强度、刚度、轻量化为约束条件,以响应面法为基础建立多学科多目标优化方案。运用Hypermesh建立有限元模型,通过Radioss进行计算,并以Hyperstudy为优化平台。采用正交实验设计对优化变量进行灵敏度分析,运用拉丁方实验设计获取采样数据点,利用移动最小二乘法构建响应面模型,结合多学科、多目标优化设计方法进行结构优化,实现提高车架结构特性和摩托车动态特性的目标。
Taking motorcycle strength, stiffness and light weight as constraints, a multidisciplinary and multi-objective optimization program based on response surface methodology was established. The finite element model was established by Hypermesh, calculated by Radioss and optimized by Hyperstudy. Orthogonal experimental design was used to analyze the sensitivity of optimization variables. Latin square experimental design was used to obtain sampling data points. Moving least square method was used to construct response surface model. Combined with multidisciplinary and multi-objective optimization design method, the structure optimization was carried out to improve the frame structure Features and objectives of motorcycle dynamics.
