| 摘 要： | 将气囊缓冲过程分解为绝热压缩和排气释能2个过程,从热力学和运动学方程出发,建立考虑降落伞阻力影响的缓冲气囊的解析分析模型。基于该模型,对立式气囊的缓冲特性进行研究。结果表明：降落伞阻力对缓冲性能有微小影响,在计算中可以忽略。在理论分析的基础上给出了系统质量与气囊初始体积比的最优值,探讨了排气口固定型与可控型气囊的缓冲特性及其应用优劣。

| Abstract: | A normal soft landing process with a gas-filled bag can be decomposed into two physical stages,one is an adiabatic compression of airbag and the other is a release of landing shock energy.Based on the kinematics and thermodynamics equations,an analytical model of a soft landing airbag considering the effect of parachute drag is developed.Then,this model is used to investigate the cushioning characteristics of a vertical cylinder airbag.The result indicates that the parachute drag has slight effect on cushio... |
