深度混合动力汽车NVH问题的研究进展

Research Progress on Deep Hybrid Vehicle NVH Problem

随着科技的发展,混动汽车已被公认为是21世纪世界汽车工业改造和发展的主要方向。混合动力汽车具有新的部件、动力系统,传动系统及运行模式,虽然其降低了传统内燃机的掩蔽噪声,但因其整车结构和相关系统的变化,致使整车在振动噪声方面出现了一系列的新问题。因此针对性地列举了混合动力汽车存在的NVH问题,分析了车内振动、噪声的产生原因及传递路径,提出了振动噪声的控制方法,最后对混合动力汽车NVH问题的解决技术作出了展望。

With the development of technology, hybrid vehicles have been recognized as the main direction of the 21st century, the world automobile industry transformation and development. Hybrid cars have new parts, power system, transmission system and operation mode, although it reduces the noise which was made by the traditional, internal combustion engine, but because of changes in vehicle structures and associated systems, resulting in a series of vehicle in terms of vibration and noise new problems. Therefore, it listed the targeted hybrid vehicle NVH problems , analyzed the causes and transmission path of the vehicle vibration, noise, vibration and noise control method, and finally made a prospect to the hybrid vehicle NVH problem solving techniques.
