汽车NVH基础与发动机影响

Vehicle NVH Foundation and Engine Impact

文章在讨论NVH基本概念和理论的的同时,相应的以汽车发动机为研究对象,对发动机转速、扭矩、产品设计精度、燃烧状态、排气和点火频率等数据进行讨论与研究,了解其产生振动或噪音产生的原理。对以后NVH的研究与发动机的研究,提供一些参考。

While discussing the basic concepts and theories of NVH,this paper takes the automobile engine as the research object,discusses and studies the data of engine speed,torque,product design precision,combustion state,exhaust and ignition frequency,and understands the principle of vibration or noise.Some references are provided for the future research of NVH and engine.
