通过拉伸试验研究了不同组织结构不锈钢纤维织物的电阻与应变之间的关系,观察到不锈钢织物的电阻变化依赖于不同的组织结构,线圈转移少、接触电阻变化大的织物有利于提高电阻响应的灵敏度和重现性。另外不锈钢纤维织物的相对电阻变化还与加载条件如最大循环应变、加载速率等相关。
The relation between resistance and strain of Stainless Steel (SS) fabric in its different structures were studied through tensile experiments. It is found that the resistance change of the fabric depends on the structure. The decrease of the loop shift and the increase of the change of the contact resistance between yarns are beneficial to improving the repeatation and sensitivity of the relative resistance for the fabric. On the other hand, the relative resistance change depends on the loading condition, such as the maximum cycle strain and loading speed in actual operation.
