摘要:
汽车驾驶室系统的怠速振动是整车NVH性能的重要组成部分.为了满足NVH性能要求,考察模拟实际约束的荣威950型汽车驾驶室系统(空调系统总成、脚踏板总成、转向柱总成、仪表台总成、中控台总成、电器线束系统)的动态特性,采用随机白噪声激励、周期性扫频激励和脉冲激励(锤击)对驾驶室系统及子结构进行模态分析,通过PolyMAX算法获得了前3阶固有频率、阻尼和振型,对比分析其模态参数可知,随机白噪声激励效果最好,并改进其子结构的特性,从而避开整车的激励频率.
Abstract:
Idle vibration of automotive cab system is an important part of vehicle NVH performance. In orderto meet the requirements of NVH, the dynamic characteristics of the practical constraints of Roewe 950 cabsystem which consists of air conditioning system assembly,a pedal assembly,steering column assembly,as-sembly,instrument panel console assembly,electrical wiring system are studied using random white noise,pe-riodic scanning incentive,pulse excitation ( hammer) to the modal analysis of the cab system and sub struc-ture,through the PolyMAX algorithm to obtain the first three natural frequencies,damping and mode.Com-parison and analysis of the modal parameters obtained from random white noise excitation is best,and im-proved properties of the sub structure,so as to avoid the excitation frequency of the vehicle.
