In the process of operation,the magnetic suction wall-climbing robot has some problems,such as overturning due to insufficient adsorption force and blocking movement due to excessive adsorption force.On the basis of designing the adsorption de-vice into a magnetic bridge structure,the influence factors of permanent magnet magnetic force are calculated by theoretical for-mula with the hull deconstructing and climbing robot as the research object.The finite element magnetic force analysis of the ad-sorption device is carried out by using ANSYS Maxwell software.The simulation data were fitted into a curve,and the feasibility of the finite element method was verified by comparing with the experimental data,and the variation rules of the influence of such factors as the cross-section area and thickness of permanent magnet,the gap between permanent magnet and hull surface,the thickness of yoke iron and the thickness of steel plate on the magnetic force in different intervals were summarized,which provided the basis for the selection of permanent magnet adsorption device for robot and the calculation and adjustment of the adsorption force.
