【摘要】:目的分析主輔式氣囊排氣口面積與開(kāi)啟氣壓閾值對(duì)氣囊沖擊加速度、速度等緩沖特性產(chǎn)生的影響,以提高氣囊緩沖性能。方法根據(jù)動(dòng)力學(xué)與熱力學(xué)相關(guān)理論建立排氣口有開(kāi)啟閾值的主輔式氣囊理論模型。結(jié)果增大主氣囊排氣口面積可使載荷加速度第1峰值減小,第2峰值增大,增大主氣囊排氣閾值效果相反;增大輔氣囊排氣口面積,載荷第2加速度峰值減小,增大輔氣囊排氣閾值效果相反。結(jié)論通過(guò)文中的解析模型合理設(shè)計(jì)了主、輔氣囊排氣口面積,對(duì)主氣囊排氣口設(shè)開(kāi)啟閾值可有效降低氣囊過(guò)載,提高了氣囊緩沖性能。
[Abstract]:Objective to analyze the effect of air outlet area and opening pressure threshold on cushion characteristics such as impact acceleration and velocity of airbag. In order to improve the cushion performance of airbag, according to the theory of dynamics and thermodynamics, the theoretical model of airbag with opening threshold was established. Results the first peak value of load acceleration can be reduced by increasing the area of exhaust port of main airbag. With the increase of the second peak value, the effect of increasing the exhaust threshold of the main airbag is opposite, the peak value of the second acceleration of the load decreases with the increase of the area of the exhaust port of the auxiliary airbag, and the effect of increasing the exhaust threshold of the auxiliary airbag is opposite. The area of the auxiliary airbag vent and the opening threshold for the main airbag vent can effectively reduce the airbag overload and improve the airbag buffer performance.
