Abstract：The process of soft landing divided into two parts, the process of airbag attenuation and the process of contact between the cargo and ground. In the first process, based on the energy conservation principle and thermodynamic equations, an analytical model of airbag attenuation system was established, then the attenuation properties could be got, and the cargo’s velocity and rotation angle before contact could be computed; in the second process, based on the theory of rigid-body dynamics and contact dynamics, an contact model between ground and the cargo with level initial velocity was built, the cargo’s velocity and rotation angle after impact could be got, then the stability of soft landing could be judged.
