Abstract


Rapid design of mechanical products for enhanced manufacturing enterprises in the increasingly fierce competition in the market conditions , the ability to respond to market demand quickly , take a favorable position in the market competition is important . Crawler crane development status , introduced the theory of the rapid design of mechanical products , methods , rapid crawler crane design technology system based on the integration of multi-technology . The main research work include : the study of the characteristics of the knowledge representation and mechanical product design knowledge , and the introduction of object-oriented thinking , analysis of the advantages of object-oriented thinking to express complex mechanical product design knowledge in the field of mechanical product design , drawn machinery products object-oriented representation of design knowledge , design object scalable knowledge integration architecture . Research based , to combine parametric design technology with modular technology , based on the secondary development of methods of the ActiveX Automation technology and 3D CAD Solid Edge object hierarchy gives the knowledge-driven design approach based on object-oriented expression , realized knowledge of CAD combine to form a the open integrated knowledge model and CAD model knowledge-driven rapid design system . Summarizes a series of problems encountered in the course of the study , including the rules of design knowledge expression storage file format , the division of product modules , automatic assembly parametric generation model , given a feasible solution for large machinery products knowledge-driven rapid design technology accumulated practical experience . In the field of construction machinery , crawler crane is a relatively mature product , clear framework of its structure , more perfect design optimization , while there are on the market to respond quickly to urgent requirements . The preparation of the crawler crane rapid design system design example demonstrates the feasibility , technical personnel can easily operation critical dimensions of the design objects complicated the design process of the design parameters of the object design , 3D model generation , and automatic assembly relieve designers work pressure , shorten design cycles , reduce design costs , and effectively avoid design errors , make the new products more competitive .
