利用几何非线性有限单元法对温控器用片弹簧参数进行了数值计算,并通过与实际测试结果的对比,验证了基于几何非线性有限单元法求解温控器用片弹簧参数的可行性和正确性。在此基础上,运用MATLAB优化工具,对片弹簧的结构尺寸进行了优化设计。然后建立触头弹跳的ADAMS仿真模型,并利用激光位移测试方法对模型进行了验证。最后利用ADAMS软件对温控器进行触头弹跳仿真分析。结果表明：基于几何非线性有限单元法优化设计的片弹簧能有效抑制动触头的弹跳。

英文摘要：

A geometrically nonlinear finite element method was applied herein to the numerical calculation of the flat spring used in a thermostat.The calculation results were verified by comparison with experiments.Then the optimal design of the flat spring＇s construction parameters were completed by using the MATLAB optimization toolbox.At last,the contact bounce of the thermostat was simulated by ADAMS.The results show that the flat spring which is designed optimally based on the geometrical nonlinear finite element method can prevent the contact bounce effectively.
