中文摘要:
      文章以一TRIMMED车身为例,首先进行车辆车身板件导纳和声腔模态分析,识别出车身板件导纳较高的频率和声腔模态耦合的频率,通过板件形貌优化分析改进板件结构设计,改进板件导纳性能以避开声腔模态频率,进而使得车辆声学灵敏度性能得到改进,满足目标要求。
英文摘要:
      In this paper,taking a TRIMMED body as an example,firstly to make vehicle body panels admittance and tune cave modal analysis,and to identify the higher frequency of body panels admittance and the frequency coupling with tune cave modal.Through the panels topography optimization analysis to improve panels design,to improve performance of panels to avoid the tune cave modal frequency,thus the vehicle acoustic sensitivity performance has been improved to meet the objectives and requirements.
