摘要 现代工程机械工作时承受载荷的情况日益复杂，并且向着高速高载的趋向发展。它们各部分的结构在工作时需要通过严密的安全性监测，以确保整个工作系统在安全的状态下进行工作。应变测量技术是能满足工程结构的各种监测要求的一种应用技术，并且实用性强，操作简便。而其中技术最完善和成熟，并且在结构监测中最广泛应用的是电阻应变测量技术。
本论文以A型简易门式起重机为测试对象，并给予起重机固定的工作起重量。通过计算确定其各部分结构的危险点，并以此为测点，应用DH3817动静态应变测试分析系统，测试该起重机在工作时各测点的应力应变，发现当吊重位于主梁跨中时起重机处于最危险工作状态，然后针对在最危险工作状态下的危险点进行强度和稳定性校核，判断出该起重机在给定的工作条件工作时处于安全状态。
随着电阻应变测量技术朝着多点、高精度、数字化、自动化和数据自动处理的方向发展，一定会在的结构健康监测中扮演更重要的角色。

关键词 应变，电阻，危险点，应力

Abstract: The condition bearing loading is gradually complicated when modern engineering machinery works , develops and towards the tendency that high speed height is loaded with. Their every part structure requires that system carries out a job under safe circumstances by the fact that close security monitors, to ensure the entire job when working. Strain measurement technology is that one kind of applied technique, and pragmatism monitoring call for is strong , operation is simple and convenient can satisfy the engineering structure various. Technologies among them are perfect and mature but, in and that structure monitors the broadest application of middle's is electric resistance strain measurement technology. The thesis takes simple A type portal crane as testing marriage partner , gives and the fixed job of crane getting weight. And then and by the point calculating the danger ascertaining whose every part structure, take this as measure point, DH3817 applying moves static
