摘　　要：随着石油机械设计不断发展,应变电测技术逐渐广泛应用在实验应力分析中。该技术中,最为重要的部件就是电阻应变计。电阻应变计具有尺寸小、重量轻以及灵敏度高等诸多优势,在复杂的工作环境中稳定性也较强。而石油井的工作环境十分恶劣,电阻应变计的结构强度中的不稳定性因素又较多,因此在实际的石油机械工作中,需要核对设备的强度,以实现设备的安全评估。With the continuous development of petroleum machinery design, strain electric technology is increasingly widely used in experimental stress analysis. In this technique, the most important component is the resistance strain gauges, resistance strain gauges have a small size, light weight, and sensitivity of many advantages, in a complex working environment stronger stability. The oil wells in the working environment is very bad, the structural strength of resistance strain gauges of more instability factors, therefore, in the actual work in the oil machinery, equipment needs to be checked for strength, to achieve the safety assessment of the device.
