某车型怠速开空调共振现象优化

Optimization of Resonance Phenomenon in Idle Air-conditioning on of a Vehicle

通过对激励源、传递路径、响应点的振动测试,以及ADAMS动力总成刚体模态计算,发现压缩机工作基频和动力总成刚体模态耦合是某车型怠速开空调共振原因。通过优化压缩机速比及其运行基频,解决此车型开空调共振问题,并用测试结果验证其有效性。

Through the vibration test of source,path and receiver,and the rigid body modal calculation of power assembly by ADAMS.It is found that the coupling of the fundamental frequency of the compressor working and the rigid body mode of the power assembly is the case of the resonance of a certain type vehicle,when in the idle airconditioning on.By optimizing the compressor speed ratio and its running frequency,the resonance
