【摘要】 将被动平衡的回转机械视为一个线性系统,根据线性系统满足叠加原理的特点,采用试配重的方法,利用一般测试仪器,测试出原始不平衡引起的振动幅值与基准相角和试加配重后引起的振动幅值确定不平衡质量大小,进而减轻设备的振动。更多还原

【Abstract】 This paper regards rotary machine as a linear system. The paper introduces the application of the way of mass distribution by testing on basis of the features that the linear system meets superposition principle. The field balancing of rotors is realized by adopting normal test apparatus to determine the amplitude and phase caused by original unbalance mass and the ones caused by adding the mass.更多还原
