摘　　要：文章采用LMS设备,对某基础皮卡和改款皮卡车型进行了详细的噪声、振动与声振粗糙度(NVH)性能测试对比分析,分别开展了动力总成怠速和加速工况下的NVH噪声对比分析、车内噪声NVH对比分析、方向盘振动NVH对比分析及座椅导轨处的NVH对比分析,结果都显示改款皮卡车型NVH噪声和振动水平要优于基础皮卡车型,验证了优化设计动力总成部件的有效性,为提升改款皮卡车型的整车NVH性能进行了积极有效的工作。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.
