【摘要】 在旋转机械中由于偏心质量引起的强迫振动,是比较常见的现象,严重威胁到设备的正常使用。在动平衡试验中,由单盘转子、双盘子、三盘转子和四盘转子上加偏心块,由此采集挠度信号,与理论计算中由柔度矩阵公式推出的结果对比,偏差率低于5%,其实用性得到验证。更多还原

【Abstract】 In rotating machinery,forced vibration caused by eccentric quality often poses a severe threat to the normal operation of the device.In dynamic balance test,the rate of deviation is reduced to less than 5% by adding eccentric block to the single-rotor,double-plate,three-rotor and four-rotor and then deflection signals are collected and compared to the result of the theoretical calculation formula.Thus its usefulness in application is verified.更多还原
