Abstract
This paper introduces the development of vacuum suction wall climbing robots, discusses the characteristics of common suction cups and corrugated suction cups, explains the advantages and disadvantages of corrugated suction cups, establishes a suction model to verify the advantages of corrugated suction cups in terms of suction performance, achieves directional control of suction cup deformation by using different materials on the same suction cup with reference to the characteristics of pneumatic flexible structures, improves some aspects of the deficiencies of common corrugated suction cups, thus optimising the This improves some aspects of the conventional corrugated suction cups, thus optimising the stability of the robot equipped with these suction cups and strengthening the suction cup structure. The 3D model of the suction cup structure before and after the improvement is imported into the ansys finite element simulation platform, and the finite element simulation model is established through the static analysis environment for analysis. The comparison of the deformation data in all directions of the suction cup before and after the improvement, as well as the total deformation, total stress and total strain of the suction cup are obtained, which verifies the feasibility of the optimisation method.
