| 摘 要： | 应用软件Fluent的大涡模拟方法,对汽车模型的表面脉动压力进行数值模拟与分析,得到高速车辆的侧表面脉动压力.结果表明,大涡模拟脉动压力与试验结果较为吻合.在得到车外表面脉动压力之后,对车内气流噪声进行了分析.针对车内噪声的特点,选用间接边界元与结构有限元耦合求解的方法.计算在声-振分析软件SYSNOISE中进行.

| Abstract: | Numerical simulation and analysis of fluctuating pressure on outside surface around model was conducted using large eddy simulation of soft ware Fluent. It is obtained that the scattergram of fluctuating pressure on outside surface of high-speed automobile. The result shows that the scattergram of fluctuating pressure by large eddy simulation coincides with the test results. It can be concluded that the calculations are available for project but the precision of simulation need be improved. |
