摘要
文章针对某微型面包车开空调,当发动机转速在1500～2000rpm时,车内存在非常强烈的异响声进行了试验研究。通过近场测量法、分别运转法,以及阶次分析等方法,确定开空调时车内异响主要是由于空调系统高压管与车身刚性连接,导致振动传递引起的。通过重新设计高压管、更换与车身连接方式,使异响问题得到解决。用此种方法解决汽车空调系统异响噪声,具有重要的参考价值。
Article for a minivan air conditioning,When the engine speed is 1500～2000 rpm There is a very strong Abnormal sound inside what were studied,Through the near field measurement method,operation method,respectively,and order analysis and other methods,Determining the open air car abnormal noise is mainly due to the air conditioning system high pressure pipe rigidly connected with the body,Causing vibration caused by passing。By redesigning high-pressure pipe,replacement and body connection,the problem is resolved.By this method to solve the car air conditioning system louder noise,important reference value.
