摘要:
对复合车身结构的特殊性能要求导致其造型和材料与普通车身有较大不同,车身质量参数(质量、质心位置等)的变化会对整车操纵稳定性产生负面影响。该文针对某复合车身结构,选取其造型特征参数β1、β2及h为设计变量,通过整车的动力学建模与分析,采用响应面法建立了操纵稳定性、车身内部空间和车身质量与设计变量之间的非线性关系,进而采用目标规划算法对设计变量进行了优化。优化结果显示,与初步设计相比,该文方法在牺牲部分车身内部空间的条件下,使蛇形操纵稳定性提高22%,车身质量减少30 kg。
Abstract:
Due to the special performance requirements on the composite body structure,the shape and the material of the composite body are quite different from that of the common body,and the change of body quality parameters,such as the mass and the centroid position,has negative impact on the vehicle steering stability.Through taking the shape parameters β12 and h of the composite body structure as the design variables,the nonlinear relationship between the steering stability,the body internal space and the quality of body with the design variables is established by using the dynamic modeling and the analysis of the vehicle and the response surface approximation method,and the design variables are optimized by using the target programming algorithm.The optimization results show that,compared with the preliminary design,the serpentine score of the condition of stability control by the method in this paper increases by 22% with the expense of the internal space part of the body,and the body mass decreases by 30 kg.
