Abstract: In this paper, LMS equipment is used to conduct a detailed Noise, Vibration, Harshness (NVH) performance test and comparative analysis of a basic pickup truck and a modified pickup truck. The NVH noise comparative analysis of the powertrain under idle and acceleration conditions, the vehicle interior noise NVH comparative analysis, the steering wheel vibration NVH comparative analysis and the seat guide rail NVH comparative analysis are carried out respectively. The results show that the NVH noise and vibration level of the modified pickup truck is better than that of the basic pickup truck, which verifies the effectiveness of optimizing the design of powertrain components, and makes positive and effective work to improve the NVH performance of the modified pickup truck.
