摘　　要：逆子结构传递路径分析方法可以重复利用部分数据,此特点在需要重复进行振动噪声传递路径查找的场合可以有效减少工作量。基于此方法对一款车内噪声超过标杆车的开发样车进行了两次振动噪声传递路径分析,然后对动力总成悬置进行了相应的整改,使车内噪声达到标杆车水平。Partial data can be repeatedly used in inverse sub-structuring transfer path analysis. The character of the method produces an effective reduction of work load on the occasion that the vibration or noise transfer paths need to be analyzed repeatedly. The noise transfer paths were analyzed 2 times for a prototype car whose interior noise was higher than a henchmarking car, then the powertrain mounts were rectified corresponding each analysis. This work make the interior poise level of the prototype car meet that of the benehmarking ear.
