自动落窗对关门耳压的模拟与试验研究

Simulation and Optimization Research on the Ear Pressure of Automatic Window Lowering on Door Closing

随着汽车技术的发展,车载功能也越来越丰富,越来越多的车型配备了关门自动落窗的功能。为探究关门自动落窗功能对关门时压耳感的影响,利用流体力学计算软件Star-CCM+重叠网格功能建立1∶1比例模型,以1.2 m/s的关门速度作为输入,仿真结果得到自动落窗对关门时压耳感的影响,并与试验结果进行对比。结果显示关门自动落窗能够有效降低车内乘员位置耳压,并且对于驾驶员位置的影响要大于后排乘员位置。

With the development of automotive technology,the in car functions are becoming increasingly diverse,and more and more car models are equipped with the function of automatically lowering doors and windows.To investigate the effect of automatic window lowering function on ear pressure during door closing,a 1:1 scale model was established using computational fluid dynamics software Star CCM+overlapping grid function.A door closing speed of 1.2 m/s was used as input,and the simulation results were obtained to compare the effect of automatic window lowering on ear pressure during door closing with experimental results.The results show that automatic window lowering can effectively reduce the ear pressure of passengers in the car,and the impact on the driver's position is greater than that on the rear passenger position.
