摘要 利用纱网单体测试的速度与压降,拟合出纱网的阻力曲线后,就带纱网导流的天窗进行了风振噪声的仿真研究。对基础状态的车型进行了不同车速的风振噪声仿真,针对风振问题最大的车速进行了不同纱网高度和不同天窗开度的仿真。将仿真结果与道路试验结果进行对比,验证了仿真方法的可行性。 After the resistance curve of the sunroof gauze was fitted by using the speed and pressure drop from the experimental results,the simulation of vehicle sunroofbuffeting noisewas carried out.The sound pressure level of buffeting noise was obtained at different velocities for a vehicle with basic status.For the vehicle speed with the most severe buffeting,different gauze heights and different sunroof opening angleswere simulated.Finally,the feasibility of the simulation method was verified by comparing with the road test results.
