Abstract:
      Lunar soil sample bag reshaping is an important part of lunar soil sampling for lunar exploration projects.The traditional simulation analysis is based on the given geometric and material parameters in dynamic modeling.In this paper,using reverse thinking,the kinematic model of the reshaping and winding system is established under the condition that the sample bag is smoothly wound.According to the equation of motion and force analysis of the sample bag,the driving conditions and the range of motion parameters of the effective winding are obtained.The results show that the running speed of the guide sleeve is the key factor and needs to match the angular speed of the winch.By adjusting the running speed to 11.63 mm/min when the angular speed is 0.6 r/min,the overlap points and failure range of the sample bag can be minimized.These research results provide a reference for the design of the sample bag reshaping and winding system.
