摘要
本文针对汽车NVH测试评价,分别从汽车NVH关注点、评价要求和条件做了介绍,并就汽车车内噪声、动力总成悬置隔振和支架共振频率、悬挂隔振特性等方面进行了较详细的实例评价。
This paper introduces briefly about vehicle NVH evaluation methods from vehicle NVH concerns, evaluation requirements and conditions. Detailed evaluation are presented case by case for the interior noise, powertrain mount vibration isolation and bracket resonant frequencies, suspension system vibration transmissibility.
