摘要
本文通过分析乘用车车内噪声产生机理及车内噪声的构成情况 ,结合研究汽车激励源的特 性 ,讨论了影响车内噪声的主要振源和声源 ,进而得出中型客车车内噪声的分布情况和产生原因 , 提出合理的降噪技术方案 ,为中型客车的降噪工作提供参数依据。
By analyzing the noise generating principle inside passenger buses and inside noise components and studying the characteristics of automobile noise excitation, this paper discusses the main vibration source and noise source so as to obtain the noise distribution and noise generation inside medium buses. Plans for noise reduction and basis for medium bus inside noise reduction are put forward.
