摘　　要：驾驶室与车架通过驾驶室支承弹簧连接,具有复杂的弹性耦合关系。商用车的优化方法主要有尺寸优化、形状优化以及拓扑优化,这三种方法只能有效地对单个零件优化,不能对具有复杂耦合关系的汽车零件进行优化。为此,引进了结构静力模态刚度的概念,推导了其相应的算法。通过计算驾驶室各部件静力模态刚度贡献,从而可找到关键部件做为可设计元件。此方法已应用于在整车安装的环境下对驾驶室的刚度贡献分析,结果表明,本文的方法是有效的。There is the complex elasticity coupling relations,as the cab and frame are connected with cab supporting springs.The size,shape and topological optimization methods are widely used in commercial vehicle design.Above three methods only valid for individual component optimization and it is difficult to deal with auto components with the complex coupling relations.To this end the concept of structural static modal stiffness is introduced,the corresponding algorithm is also developed.The proposed method is applied to the static modal stiffness contributions of the cab.This method can be used to deal with the optimization of components in full truck assembly environment.
