Abstract
This paper explains the concept of high mileage automobile NVH(Noise Vibration and Harshness ) robustness. Based on the NVH characteristic subjective rating method, a quantitative analysis and evaluation method for NVH robustness of high mileage automobile is proposed. By using the subjective rating attenuation method of high mileage automobile NVH robustness and combine the actual parameters of three different types of cars, According to the calculation and analysis of the decline and attenuation of subjective rating attenuation method, the NVH robustness characteristics and change rules of three different types of cars at different mileage stages are obtained, which provides a reference for the NVH robustness analysis of high mileage automobile and the development of automobile NVH.
