Abstract ： In order to solve the problems such as poor climbing stability and potential safety hazards of automatic tank defect detection robot， a permanent magnet adhesion tank wallclimbing robot is designed and its adhesion characteristics are analyzed. The adhesion mechanism based on permanent magnet is designed. The staticmodelof therobotis built through the analysis of the failureof therobotatwork，and the minimum magnetic adhesion force required by the robot in normal work is calculated.In order to ensure that the minimum magnetic adhesion force is taken as the magnetic adhesion condition，the magnetic adhesion unit is designed using the linear Halbach array arrangement of five permanent magnets，and the influence of permanent magnet volume，armatureandair gap length on the adhesion force is analyzed.Through finite element analysis，a cuboid magnetic block with a volume of 30mm×30mm×30mm isfinally designed， the armature size is 150mm×54 mm×3mm ，the addition direction is positive along the Z axis， the rated air gap is 10mm during adhesion， and the minimum magnetic adhesion force is 493.02N ，which could ensure the adhesion stability of the robot.

大型儲罐是油氣能源常用的關鍵存儲設備，其在自然環(huán)境下長期使用會產(chǎn)生腐蝕、裂紋等缺陷，進一步擴展開裂則會發(fā)生泄漏甚至爆炸，導致嚴重的安全事故，因此相關法規(guī)強制規(guī)定了儲罐需定期檢測[1-2]。（剩余5475字）
