摘　　要：汽车NVH问题包含许多方面,异响是其中一个重要问题。异响指无规律且异常的声音,这些响声不同于正常车辆运行时的声音。这些异响问题对消费者来说非常重要,因为它们会直接影响汽车的质量评价。仪表板的异响是内部噪声的主要来源之一,由于距离乘员近,更容易被清晰感知,所以对仪表板异响的研究对于汽车的质量保证至关重要。文章着重阐述了异响的定义、成因和分类,并提出了评估方法和设计优化方法。The NVH problem of automobiles encompasses many aspects,among which abnor⁃mal noise is one of the significant issues.Abnormal noise refers to irregular and unusual sounds that differ from the normal sounds during vehicle operation.These abnormal noise problems are crucial for consumers as they directly affect the quality evaluation of automobiles.The abnormal noise from the dashboard is one of the main sources of interior noise,which is more easily perceived due to its prox⁃imity.Therefore,the study of abnormal noise from the dashboard is crucial for ensuring the quality of automobiles.The definition,causes,and classification of abnormal noise are discussed,and evalua⁃tion methods and design optimization approaches are proposed.
