| description | Rebound is the main problem in the landing process of the combined airbag. To solve the problem, the design method of the combined lunar landing airbag without rebound was proposed in this paper. First, a new combined airbag structure was designed to avoid dust generated by venting during landing, and the analytical dynamics model of the combined lunar airbag was established on the basis of the deformation assumptions and gas exchange relationship of the main and secondary airbags, which is validated by simulation and experiment. Then, based on the analytical model, the combined airbag was optimized under the constraint of no rebound to realize the design of the airbag without rebound. Finally, the multiobjective optimization design of the combined airbag was carried out using this method. The optimized airbag with no bouncing back and no hard landing was also obtained, of which the maximum impact acceleration was smaller than the nonoptimized one. The analytical results of the optimized airbag are in good agreement with the simulation results, indicating that the proposed no-rebound design method is effective and feasible. |
