摘　　要：文章提出了汽车NVH测试分析系统的设计方案,设计了该系统的硬件系统与软件系统。该系统以图形化编程语言LabVIEW为软件开发平台,将虚拟仪器技术运用到汽车振动测试分析当中;实现数据的采集、显示及存储,并结合SVT工具包,实现了多种分析功能,使得振动分析更加精确,缩短了测试和信号处理周期。This paper presents the system design plan of vehicle NVH testing, the systematic hardware system and software system of the virtual vibration. This system regards figure programming language LabVIEW as the software developing platform, applies the technology of the virtual instrument to the vibration testing,and carries out the acquisition,display and storage of the data. With the SVT Toolkit, it can carry out many kinds of analysis functions and make the vibration analysis more accurate, thus shortening the period of testing and processing of the signal greatly.
