Parachute unfolding process stability assessment method of Mars parachute bag combination

Abstract

The invention discloses a parachute unfolding process stability assessment method of a Mars parachute bag combination and relates to a parachute unfolding process stability assessment method and belongs to the technical field of aerospace. The parachute unfolding process stability assessment method adopts six-degree-of-freedom modeling, can conduct simulation analysis on center of mass motion in the parachute unfolding process and can also conduct simulation and assessment on parachute cabin gestures and the stress situations of hanging belts. Due to the fact that the established six-degree-of-freedommodel of the parachute cabin combination is simplified, the flow field analysis and flexible body modeling process can be omitted on the premise that it is ensured that simulationconforms to the actual physical situation, and the assessment and simulation efficiency is improved. The parachute unfolding process stability assessment precision and assessment efficiency of the Mars parachute bag combination can be improved, data support is provided for parachute and cabin parameter configuration, and the times and design costs of physical testing are reduced. In addition, the parachute unfolding process stability assessment method is feasible to different cabin type Mars landing tasks and is high in repeatability and wide in application range.
