模拟指压作用下驾驶员安全气囊盖板的刚度特征研究
|
摘要
驾驶员安全气囊盖板不仅需满足气囊起爆性能要求,同时也需满足按压喇叭时具有足够刚度的要求。而盖板刚度目前都只是通过主观按压评价,没有定量的试验检测和数据描述。通过对出现塌陷问题的驾驶员安全气囊和其他不同车型驾驶员安全气囊盖板进行主观按压评价和刚度试验,得出定量描述盖板刚度的假设,再通过增加加强筋提升塌陷问题盖板刚度后进行主观按压评价和刚度试验,验证假设成立,得出盖板刚度测试方法和定量描述方法。
The cover of driver airbag should not only satisfy the performance request of deployment,but also satisfy the sufficient stiffness while pressing on horn. However, the stiffness of the cover is only evaluated by subjective pressure at present, and there is no quantitative test and data description. Through the subjective pressure evaluation and stiffness test of the driver airbag and other different models of the driver's airbag cover, the assumption of the stiffness of the cover was obtained, and then the stiffener was used to increase the stiffness of the cover. The subjective press evaluation and the stiffness test were carried out, and the verification hypothesis was established, and the test method of the cover stiffness and the quantitative description method were obtained.
