It is well known that the parachute deployment process is the most critical part of the equipment before landing.

摘要

It is well known that the parachute deployment process is the most critical part of the equipment before landing. In this paper, a structural dynamics finite element model is established to investigate the parachute deployment process of an air-dropped multiple launch rocket canister. Initial attitude of the equipment system with constrained loads at the suspension points of the cargo platform Multibody dynamics calculations obtained as boundary conditions for the finite element model. The dynamic response and structural stresses of the equipment system when impacted by parachute deployment are obtained by simulation. The results show that although large parachute clusters can significantly reduce the landing speed and stabilize the swaying attitude of the equipment system, the resulting shock overload can threaten the structural safety of the equipment. The simulation results have certain reference significance for heavy equipment airdrop safety analysis, and the results provide a practical basis for the follow-up parachute optimization design collocation.
