摘　　要：针对一种新型测试靶车的伸缩悬架结构,先后通过受力计算与联合仿真的方法得到弹簧刚度参数,并加以分析设计。首先分析伸缩悬架的结构特征,通过建立1/2悬架的力学模型,分析得到弹簧刚度与靶车承载质量的关系。接着,在此基础上利用ANSYS-ADAMS联合仿真得到不同弹簧刚度下悬架关键部件——摇臂的应力应变情况。结合仿真结果与靶车实现过载保护的功能要求,选择60 N/mm的弹簧刚度系数,对其加以验证,并对弹簧进行尺寸设计。For telescopic suspension structure of a new test target vehicle,spring stiffness parameters are obtained by force calculation and co-simulation,and then analyzed and designed.Firstly,structural characteristics of telescopic suspension are analyzed.By establishing a mechanical model of 1/2 suspension,relationship between spring stiffness and bearing mass of target vehicle is obtained.Then,on this basis,stress and strain of rocker arm,which is the key component of suspension,are obtained under different spring stiffness by ANSYS-ADAMS co-simulation.Combined with the simulation results and the functional requirements of overload protection,spring stiffness coefficient of 60 N/mm is selected and verified,and dimension of spring is designed.
