Abstract：Aiming at the problems of insufficient adaptability to stairs and bulky volume of traditional climbing mechanisms such as wheel group types,wheel shoe compound types and wheel leg compound types,taking climbing stairs as the primary task and the design purpose,a new type of stair obstacle surmounting mech-anism Archimedean spiral deformation wheel was proposed.This deformation wheel not only adapts well to the complex environment of stairs,but also combines the strong maneuverability of wheeled travel mechanisms with the superiority of spiral travel mechanisms.The deformation wheel mechanism and overall assembly plan were designed by using the SoildWorks software,the parameters were calculated,the data of the deformation wheel was analyzed based on the motion environment and obstacle crossing process,and the process of the deformation wheel climbing continuous steps was optimized.Finally,the Adams software was applied to simulate and analyze the obstacle crossing process of the deformable wheel,and a comparative simulation was conducted between the planetary wheel and the deformable wheel,indicating the effectiveness of the design and research.The simula-tion results show that the designed deformable wheel has strong maneuverability and obstacle crossing ability.
