Abstract
This paper introduces the basic theory of the work transfer path analysis and transfer path analysis,and establishes the working condition of transfer path analysis model and finds the specific problem of the source by using this method.On the basis of monitoring the vibration of main passive side vibration acceleration and its transmission path,it achieves the structure of pavement noise transfer path test.Transfer path analysis results show that under 250 Hz,the fitting method is consistent with the measured sound pressure near the main peak,and then it verifies the accuracy of the model.Based on this model,it narrows the scope of the search path and analyzes the human ear noise in 100 ～ 250 Hz contribution amount of each transmission path.关键词
