新能源汽车与内燃机的汽车噪声特性分析

随着我国社会经济不断发展,给汽车行业带来巨大的发展空间,尤其是内燃机汽车和新能源汽车,但随之带来很多方面的问题,如低噪音引发的行人安全问题,为了有效解决这些问题,本文以新能源汽车在中国发展现状和世界各国由新能源汽车带来的低噪音引发行人安全问题为基础,进一步研究了四种汽车在行驶过程当中出现的噪音,来解释在产生噪音后,根据不同速度来判断会引起汽车噪声可能出现的变化,从而判断会不同类型汽车所产生的噪声差异。

Analysis of Vehicle Noise Characteristics of New Energy Vehicle and Internal Combustion Engine

With the continuous development of China's social economy,it has brought great development space to the automobile industry,especially the internal combustion engines and new energy vehicles,but it has brought many problems,such as pedestrian safety caused by low noise.In order to effectively solve these problems,this paper is based on the development status of new energy vehicles in China and the pedestrian safety problems caused by low noise from new energy vehicles around the world.Furthermore,this paper studies the noises of four kinds of cars in the driving process to explain that after the noises are generated,it can be judged according to different speeds that will cause the possible changes of car noises,so as to judge the differences of noises generated by different types of cars.
