摘要
NVH性能是乘用版皮卡车型重要的性能构成,较低的车内振动水平及良好的声品质是乘用版皮卡车型NVH性能设计必然品质追求。文章针对某自主开发乘用版皮卡和竞品皮卡两款车型,开展了加速工况100 km/h下的车内声压对标分析及振动对标分析,同时开展了巡航工况下的二者的车内振动与声品质对比分析,试验结果表明,两款皮卡车型NVH性能满足目标要求。
NVH performance is an important performance component of a passenger pickup truck.Low interior vibration level and good sound quality are the inevitable requirements of NVH performance design of PK.Aiming at a self-developed PK and a competitive PK,this paper carries out the interior vibration benchmarking analysis and sound pressure benchmarking analysis under the acceleration condition of 100 km/h,and carries out the interior vibration and sound quality benchmarking analysis under the cruise condition The test results show that the NVH performance of the two PKs meets the target requirements.
