摘要

摘要: 斜圈弹簧刚度是其力学性能的重要指标之一,由于结构的特殊性目前尚无高效高精度的斜圈弹簧刚度测量手段。为此提出了一种斜圈弹簧刚度测量原理及相关计算方法,并设计了相应的测试装置。为了验证测量方案的可行性,基于Ansys软件平台建立斜圈弹簧有限元模型,考虑几何非线性和接触问题进行了有限元仿真,并在拉压力试验机上进行准静态加载实验。通过有限元仿真结果与实验结果的对比分析,本测量方法可有效的测量出斜圈弹簧的刚度,并绘制出载荷位移曲线。

Abstract: Canted coil spring stiffness is one of the most important indicators of its mechanical properties. Due to its special structure, there is not high efficiency and high precision instrument for stiffness measurement of canted coil spring. The canted coil spring stiffness measuring principle and related calculation method are proposed, and the corresponding test equipment is designed. In order to verify the feasibility of the present measuring scheme, a finite element model for canted coil spring based on ANSYS software is established, the simulations are carried out by considering geometric nonlinear and contact problem, and the experimental verification under quasi static loading are conducted on a tension and compression testing machine. The finite element simulation results and the experimental results show that the canted coil spring stiffness could be measured effectively with the present method, and the load-displacement curves for the canted coil spring could be efficiently obtained.
