电阻式应变计在封装成型过程中，通常利用圆柱螺旋压缩弹簧工装对其进行加压。由于工装弹簧在制造过程中存在线性比不准确，在使用过程中易产生疲劳破坏，以及微小的冲击振动等问题，因而直接影响电阻应变计的最终质量。基于Solidworks软件环境，对工装弹簧进行参数化建模，并利用Solidworks Simulation 对其刚度、疲劳以及频率进行分析，计算出工装弹簧的刚度、疲劳寿命及频率。结果表明，工装弹簧的刚度仿真分析值与理论值误差约为4．17％，在工程误差范围内，工装弹簧的最大疲劳寿命约9000次，工装弹簧最小频率约100．3 Hz。仿真数据为弹簧工装的安全使用和检测维修提供了可靠依据。

Cylindrical helical compression spring fixture is usually used to put pressure on the electric resistance strain gages during the process of their encapsulation molding .The tooling spring has some problems such as inaccuracy of linear ratio in the manufacturing process , easily emerging fatigue failure and small im-paction and vibration during use , which has direct effects on the final quality of the electric resistance strain gages.For these problems , the parametric modeling of tooling spring is established by making use of Solid -works software , and the finite analysis of its rigidity , fatigue and frequency are completed by Solidworks Simu-lation, which calculates the stiffness , fatigue life and frequency of the tooling spring .Analysis results show that the error of simulation result and theoretic result of spring rigidity is about 4 .17%, within the engineering permissible range, the maximum fatigue life is about 9 000 times, the minimum frequency is about 100.3 Hz. The simulation data provide a reliable basis for safe use and maintenance of the spring fixture .
