【摘要】 采用武汉理工大学开发的TPN轮胎花纹噪声仿真系统对不同规格轮胎花纹噪声进行仿真分析,并与实测数据进行对比。结果表明:由于实测噪声包括非花纹噪声,轮胎噪声实测1/3倍频程直方图与仿真图有一定差异;实测与模拟轮胎噪声A计权声压级变化趋势基本一致。更多还原

【Abstract】 The tread patterns noise of different tire were simulated with TPN tire tread pattern noise simulation system developed by Wuhan University of Technology,and the simulation results were compared with testing data.Since the measured noise included non-pattern noise,the 1/3 octave band histogram of measured noise had some difference with the simulated result.However,the mea-sured A-weighted sound pressure levels of tire noise were basically in the same trend with the simulated results.更多还原
