摘要
对离心通风机安装架上减振垫处连接点进行了导纳试验研究。试验结果表明,在1/3倍频程频率范围为2～3150Hz内,该通风机与电力机车连接点处的导纳特性曲线总体变化比较平缓,达到了减振的设计效果。
The mobility test of the contact points on the mounting structure adjacent shock pad is carried out.The test results show that the change of the mechanical mobility curve at the contact points of ventilation and locomotive is gentle and the damper effect was good.
