APPLICATION OF ULTRASONIC TECHNIQUE IN DIRECT MEASUREMENT OF BOLTS AXIAL STRESS[J]. Thermal power generation, 2000, (1): 53-55. DOI: 10.19666/j.rlfd.2000.01.012.
螺栓轴向应力的超声波测量
摘要
一些设备上的关键螺栓安装或紧固时
人们希望能直接准确地控制螺栓的轴向应力
以保证其工作的可靠性
这点对电力设备尤其具有重要的意义。用超声波技术研制成功了一种可直接测量螺栓轴向应力的螺栓轴向应力仪
该仪器可广泛应用于关键设备的紧固测试
进而精确地控制螺栓轴向应力。对用超声波技术测量螺栓轴向应力的基本原理进行了介绍
并给出了超声波螺栓轴向应力仪应用实例。
Abstract
This paper presents the basic principle for measuring bolt-axial stress by ultrasinic technique and case study on its application.Direct measurenent equipent to determine bolt axial stress by using ultrasonic technique has been developed.This equipment can be widely used to measure the fastenning of key components so as to accurately control bolt-axial stress.
