对于行驶速度大于30 mph(注:1 mph=1.609 km/h)的车辆,行驶噪声包括了多方面因素。其中汽车发动机系统和排气系统的噪声,通过长期的改进升级,已经得到了有效控制。相比之下,轮胎与路面相互作用产生的噪声成为了交通噪声的重要来源。开发了高效的边界元方法(BEM)/有限元方法(FEM)模型,分析预测典型的载重汽车轮胎与路面相互作用产生的噪声,并且与试验场地测试的
For vehicles traveling at speeds greater than 30 mph (Note: 1 mph = 1.609 km / h), driving noise includes many factors. Among them, the noise of automobile engine system and exhaust system has been effectively controlled through long-term improvement and upgrading. In contrast, the noise generated by the tire-road interaction becomes an important source of traffic noise. An efficient Boundary Element Method (BEM) / Finite Element Method (FEM) model has been developed to analyze and predict the noise generated by the typical truck tire-road interaction and to be tested against the test site
