车门开度对关门时车内人耳位置峰值压力的影响

为了进一步探究关门压耳感的影响因素,进而解决目前车门关闭时车内压力过大的问题。利用计算流体力学软件Star-ccm+的重叠网格技术分析关门时不同车门开度对车内峰值压力的影响。将不同车门开度的瞬时速度作为仿真计算的输入,得到该车型关门耳压计算值,并通过试验测试相同状态下实际关门耳压。仿真结果与测试结果对比显示车门开度35°与70°状态下得到的关门耳压基本一致,车门开度对关门时车内峰值耳压影响较小。在以后的测试和仿真模拟过程中可以快速提高仿真研究的进度和工作效率。

Effect of Door Opening on Peak Pressure of Ear Position in the Car When Closing

In order to further explore the influencing factors of the sense of pressure when closing the door,and then solve the problem of excessive pressure in the car when the door is closed.The effect of different door openings on the peak pressure in the car when closing the door was analyzed using the overlapping grid technology of the computational fluid dynamics software Star-ccm+.The instantaneous speed of different door openings is used as the input of the simulation calculation to obtain the calculated door closing ear pressure value,and the actual door closing ear pressure is tested through the test.The comparison between the simulation results and the test results shows that the door opening ear pressures obtained in the state of the door openings of 35°and 70°are basically the same,and the door opening degree has little effect on the peak ear pressure in the vehicle when the door is closed.In the future testing and simulation process,the progress and efficiency of simulation research can be quickly improved.
