Abstract:
Case representation and retrieval is the base for case-based mechanical product design.The hierarchical decomposition tree is improved in product case frame models,and it can be decomposed and combined ulteriorly at discretionary node.A method for representing node case based object-oriented technique is presented according to the hierarchical decomposition tree of the product case.A two-stage case retrieval strategy and its algorithm which includes preelection of case,matching of objective case and spare case are proposed.An example of automatic mechanism design in small arms is given,which elevates the efficiency of the case retrieval.
