| 摘 要： | 为了提高钢板弹簧的仿真计算精度，对钢板弹簧的片间摩擦系数进行参数辨识，确定一组等效摩擦系数。首先建立钢板弹簧的有限元模型，采用响应面法和线性规划方法对钢板弹簧的片间摩擦系数进行辨识，得到一组摩擦系数，然后利用ANSYS软件计算钢板弹簧的刚度特性，并与试验结果进行对比，确定模型仿真计算结果的准确性。

| Abstract: | For improving the simulation accuracy of leaf spring, a group of equivalent friction coefficient is determined through the identification of friction coefficient of inter-leaf. Firstly the FE model for leaf spring is set up, and a group of friction coefficient is determined with response surface method and linear programming method. Then using the ANSYS to analyze the stiffness of leaf spring and its accuracy is verified by tests. |

| Keywords: | leaf spring friction coefficient parameter identification response surface method |
