基于有限元分析柔性织物键盘开关的疲劳性能
Analyzing fatigue performance of flexible fabric keyboard switch based on finite element
摘要
Abstract
In order to explore the fatigue properties of flexible fabric keyboard switches, according to its organizational structure, the geometric model of flexible fabric keyboard switch was established by using Pro/E 5.0. Based on the actual material properties, the fatigue life of the flexible fabric keyboard switch was simulated by the static structure module of ANSYS Workbench 15.0, and the stress distribution and fatigue property of flexible fabric keyboard switch during fatigue damage were obtained. The fatigue life of flexible fabric keyboard switch is measured by using composite precision life tester, and the simulation result was verified by the experiment. The result shows that the fatigue damage of fexilde fabric keyboard switch mainly appears in the center of warp yarn. The life simulated by finite element is 37927 times, and the experimental life of the test is about 30000 times. The good agreement between the FEM results and experimental results proves the validity of the model. This provides guidance for the improvement and application of flexible fabric keyboard switch.关键词
