摘　　要：利用ANSYS软件对底盘结构进行静态分析得出了基础结构性能与质量,采用模态分析研究底盘结构易发生共振位置所在。基于有限元分析结果,以底盘结构的最大应力、最大变形、质量和固有频率为优化目标,以基础底盘结构的相关尺寸参数作为优化设计变量,对底盘结构进行响应面优化分析,确定了最佳优化参数的底盘结构。其与优化前相比:最大应力与最大变形分别降低了31.5%和74.3%,并且质量也相比优化前降低了1.3%,底盘的一阶固有频率相比优化前提升了50.4%。ANSYS software is used for static analysis of the chassis structure to derive the performance and quality of the base structure,and modal analysis is used to study where the resonance of the chassis structure is prone to occur.Based on the finite element analysis results,the maximum stress,maximum deformation,mass and intrinsic frequency of the chassis structure are taken as the optimization objectives,and the relevant dimensional parameters of the basic chassis structure are taken as the optimization design variables to carry out the response surface optimization analysis of the chassis structure,and the chassis structure with the best optimization parameters is determined.Compared with the pre-optimization,the maximum stress and maximum deformation are reduced by 31.5%and 74.3%,respectively,and the mass is also reduced by 1.3%compared with the pre-optimization,and the first-order intrinsic frequency of the chassis is improved by 50.4%compared with the pre-optimization.
