摘要
叙述了虚拟仪器技术在发动机噪声测试中的应用,分析了发动机的噪声源,设计和选择了噪声测试系统的硬件和软件部分.通过对某一款发动机的实验,完成了怠速工况,经济工况下以及最大扭矩下的测试实验,并进行了数据分析,证明了基于虚拟仪器技术的噪声测试系统能够满足基本的测试分析需要,为在发动机噪声测试领域采用先进的虚拟仪器测试技术提供了理论和实践依据.
This article discusses the application of virtual instrument in the measurement of automotive engine noise, analyzes the source of the noise and designs the hardware and software of the measurement system. In addition, by doing rearches on an engine, we have done the tests under different conditions, and have analyzed the data which can prove that the new measurement system can meet all the basic test requirement, which provides the foundation of the advanced virtual instrument test system to be used in the area of automotive engine system.
