摘要：The disassembly of interference fit is a difficult process for remanufacturing engineering, which frequently causes multiple types of friction damage, such as scratches, furrow, and adhesion on the surface of parts. The form and size of surface damage directly affect the cost of remanufacturing repair. If the damage is less than a threshold, the part can be directly used for assembly without repairing. This condition represents a nondestructive disassembly, which is the goal of remanufacturing disassembly for interference fit. In this study, varying degrees of disassembly surface damage of interference fit are obtained by experiment and detected by TRIMOS-CL3 3D surface profilometer. Six surface evaluation parameters Sv, Sp, Sq, Str, Vmp, and Sa, are selected from ISO 25178 as indexes for entropy analysis to evaluate the damage comprehensively. According to the interface state, a comprehensive evaluation threshold of nondestructive disassembly is proposed. The rationality of the threshold is verified by the load-carrying capacity experiment of the interference fit.
