In this paper, cushion process of the cylinder airbag in airdrop equipment landing system has been simulated. Based on the finite element theory, the finite element model of the airbag cushioning system is modeled by using the dynamic analysis software LS-DYNA in ANSYS, and the air bag cushion process is simulated by the corpuscular particle method. The simulated variation of airbag cushion height, cargo table acceleration meet the requirements of equipment airdrop overload. Compared with the traditional control volume method, the corpuscular particle method simulation is verified. The research results can provide reference for the engineering staff in the airbag design or reliability.
