一种增压器NVH性能的提升方法

A Method for Improving NVH Performance of a Supercharger

增压器噪声会大大降低车内声学品质,对驾驶员和乘客造成噪声干扰。文章首先对增压器的结构、原理和特性进行阐述,分析各类噪声的产生机理,并找寻提升方法,然后通过提升前后噪声对比试验验证和人员主观评价相结合,对提升方法的有效性进行判断。最终找出各类噪声的相关提升方法建议,并在具体开发产品中有效运用,且取得良好效果。

Supercharger noise will greatly reduce the acoustic quality of the vehicle,causing noise interference to drivers and passengers.This paper first describes the structure,principle and characteristics of the supercharger,analyzes the generation mechanism of various types of noise,and finds out the enhancement method,and then judges the effectiveness of the enhancement method by combining the noise comparison test before and after the enhancement with the subjective evaluation of personnel.Finally,we find out the relevant suggestions of various noise enhancement methods,and effectively apply them in the specific development products,and achieve good results.
