轻型卡车车内噪声传递路径分析

Analysis of Noise Transfer Path in Light Truck Vehicle

一般卡车行驶的时候内部都会产生噪音,噪音过大的时候难面对司机产生不利的影响,这篇文章主要对某轻型卡车车内噪声整体偏大的问题进行分析,并制订了一个实验计划"OTPA(运行工况传递路径分析)",实验结果显示,车内噪声的主要途径的贡献量。这对于车内噪声的最大值进行传递路径进行详细的研究和分析,得到最终结论是引起车内噪声偏大的主要传路径。

In general,when the truck is driving,noise will be generated internally.When the noise is too large,it is difficult to face the driver to have adverse effects.This article mainly analyzes the overall problem of excessive noise in a light truck.An experimental plan"OTPA(operational transmission path analysis)"was formulated.The experimental results showed that the contribution of the main ways of noise in the vehicle.In this paper,the transmission path of the maximum noise is studied and analyzed in detail,and the final conclusion is that the main transmission path that causes the noise in the car is too large.
