摘　　要：应用振型分解法推导出在各种扰力共同作用下基础水平旋转振动的通用计算公式,对相位差对基础振幅计算的影响以及在不同条件下第二振型对振幅计算的影响进行详细分析,对活塞式机器基础的合成振幅的计算进行讨论并提出新的计算方法。It was deduced that the general computation formulas of vibration foundation with horizontal and rocking vibration under the action of exciting forces. It was also studied in detail that the influence of phase shift and the second vibration mode on the computation amplitude of foundation under different conditions. The computation method for general amplitudes of foundation under reciprocating compressor was discussed and new computation method was proposed.
