摘　　要：运用一款试验车及轮胎,改变轮胎的气压,研究了轮胎气压对车内噪声的影响,通过频域计算的RMS值可以很好的表征车内噪声典型频段声级水平的变化趋势。试验结果表明:随着轮胎气压的增大,较为粗糙路面上轮胎低频轰鸣噪声呈减小变化趋势;轮胎空腔共振噪声呈增大变化趋势;较为平整路面上花纹噪声呈增大变化趋势。运用理论对相关的结果进行了分析。Using a test car and their tires,the influence of tire pressure on the internal noise was studied by changing the tire pressure,the trend of the typical frequency band noise level of interior noise can be characterized by RMS value through frequency domain calculation.The test results show that with the increase of tire pressure,tire low frequency booming noise shows a decreasing trend on the rough road.The tire cavity noise shows an increasing trend.Pattern noise also shows an increasing trend on the smooth road.The relevant results were analyzed using relevant theories.
