摘要
采用比利时LMS公司的Test.Lab振动噪声测试系统,对某越野车内加速轰鸣声的问题进行了测试研究。应用振动、模态、ODS等分析获知轰鸣声的根源及路径,并提出改进方案。通过手工样件对改进方案进行了验证。
The interior booming noise problem of SUVs was analyzed by using the Belgium LMS Test.Lab system. Through the analysis of vibration,modal,ODS,we obtained the source and path of booming noise,and also improved methods were carried out and were validated by the handwork component.
