Taking the anti-wear bushing sleeve as the object,based on the fracture mechanics judgment criterion-maximum principal stress criterion in ABAQUS,the simulation research on the step fracture process of the sleeve is carried out,and the lifting force required for the multi-functional tool to unlock the sleeve is calculated.The judgment criterion of maximum principal stress in fracture mechanics is analyzed theoretically.Conduct finite element analysis and modeling of the anti-wear bushing sleeve.Three different materials,4130 75K,45# steel,and 8630 MODI,are selected for simulation analysis of the sleeve.A comparative analysis is conducted on the effects of stress intensity factors,lifting forces,and stress-strain near the crack in the sleeve of three different materials,as well as their variation over time.It indicate that 4130 75K material is ultimately selected as the anti-wear bushing sleeve material,and the results can provide reference for engineering applications.
