摘　　要：压缩机是空调的核心部件,其振动特性对改善压缩机的可靠性十分关键。为研究空调外管路固定方式对压缩机振动特性的影响,本文开展了压缩机振动特性试验研究。考虑了包括空调外管路约束位置、约束数量两个变量因素;记录压缩机在30 Hz∼90 Hz的运行频率下各测试点不同方向的振动加速度。试验结果表明,适量增大约束位置与室外机的距离能更好地实现压缩机的减振效果;增加约束数量仅会在压缩机轴向减振上取得微弱效果,反而会使电机径向加速度大幅增加。The compressor is the core component of an air conditioner,and its vibration characteristics play a key role in improving the reliability of the compressor.In order to clarify the effect of the fixing method of air conditioner external pipeline on the compressor’s vibration characteristics,this paper carried out some experimental research on it.Two variable factors,including the location of the constraints and the number of constraints on the air conditioner external pipeline,were taken into account;the vibration acceleration in different directions at each test point of the compressor was recorded during the test at an operating frequency of 30 Hz∼90 Hz.The results of the test show that a moderate increase in the distance between the restraining position and the outdoor unit can lead to a better realization of compressor vibration reduction;Increasing the number of constraints achieves little vibration reduction in the axial direction at the compressor position,but will increases the radial vibration acceleration at the motor position considerably.
