【Abstract】 A new method of information-driven design for dismantling equipment is put forward based on the in-depth analysis of characteristics of dismantling equipment. The objects’ dismantling process information model is created by defining and analyzing information for dismantling equipment design,namely Customer Needs Information( CNI),Design and Analysis Information( DAI),Physical Structure Information( PSI) and Process Variables Information( PVI). A Disassembly Sequence Planning( DSP)method is carried out in view of the stability of dismantling process. Considering the main characteristics of dismantling equipment,the interactions among its physical structure and variable information are analyzed. A mapping algorithm from customer needs information,design and analysis information to equipment’s physical structure is raised by inducing the effect of objects’ information uncertainty on dismantling device structure and building the main parameter matrix for dismantling device structure.The dismantling equipment design based on information model-driven is realized,with the purpose of designing an equipment of independence,universality and robustness. A case study of dismantling platform design for hydraulic oil cylinder is presented to testify the feasibility and practicability of the method.更多还原
