摘要
电测法是对构件进行应力分析常用的实验方法之一,具有灵敏度高、传感元件小、适应性强等特点,已经成为实验应力分析中应用最广和最有效的方法之一,并在实际工程中得到广泛的应用。依据电测法的基本原理及分析方法,以不等边角钢和工字钢为例,研究分析了在测量轴力、弯矩、扭矩等物理量时的贴片方法、理论推导及实验数据处理。为其他构件进行力学性能参数测量提供一些实验测量方法及技巧,使电测法在实际测量中得到更好的应用。
The resistance straingauge method is commonly used in the actual components of the stress analysis of the experimental method,because of its high sensitivity,small sensors and high adaptability.The testing way has became one of the most extensive and effective methods in the practical engineering.This paper introduces the composition and the working principle of the resistance straingauge method,analysing the method of attaching resistance straingauges and dealing with data.What＇s more,it can provide some skills and theoretical principle to solve some questions in other materials,which is important to the application in practice.
