1、前言——实机扭振测量的目的:自1977年1月以来,三菱公司在电力公司的协助下,针对“轴系综合设计”课题,在发电厂里对实机进行了“汽轮——发电机组轴系扭振”测量。其目的在于验证三菱公司发展的“轴系扭振设计计算法”的精度,确立能与电力系统运用协调的设计轴系的技术。(图1) 1, Foreword - Purpose of Torsional Vibration Measurement Purpose: Since January 1977, with the assistance of electric power company, Mitsubishi Corporation has carried out the “Turbine - generator shaft torsional vibration ”measurement. Its purpose is to verify the accuracy of the “Shaft Torsional Vibration Design and Calculation Method” developed by Mitsubishi Corporation and to establish the technology of designing the shafting that can be coordinated with the power system.
