为了掌握大型汽轮机叶片的机械应力,防止危险状态,开发了采用应力测定的实验诊断方法。这种方法的顺序如下:①实验室试验;②超速室试验;③运行状态试验。在②和③中,采用了遥测系统。在①中,采用了常规测量方法。本文叙述了诊断目的和测 In order to grasp the mechanical stress of large-scale turbine blades and prevent dangerous state, the experimental diagnosis method using stress measurement was developed. The sequence of this method is as follows: ① laboratory test; ② speeding chamber test; ③ running state test. In ② and ③, using a telemetry system. In ①, using the conventional measurement methods. This article describes the diagnostic purpose and measurement
