With the rapid development of automotive industry,the production output and the gross of automobile are rising rapidly.At the same time,with the amount of old automobile increasing qucikly,some problems such as resource shortage, environment pollution and so on have been concerned more and more.Automobile transmission is a very important subassembly of automobile,which affects the auotmobile dynamic characteristics and economy,control reliability and portability, transmission smoothness and efficiency etc.Therefore,how to disassemble scrap transmission of automobile for recycle and how to use in the most extent is a study hostpot in automobile "Green Technology",which is also an important research subject in the automobile field.Firstly,product disassembly design network model is built based on graph theory technology,product part disassembly sequence plan is analyzd based on analyzing products disassemble information demand,automobile transmission product modeling theoretics is summarized on the basis of disassembly information extractation and describing method,and the automobile transmission disassembly model is built.Secondly,In order to realize the product disassembly planning,automatical generating disassembly sequence theory and technology of automobile transmission is studied,product disassembly model is solved on the basis of petri net including recycling value and disassembly cost to obtain the best disassembly sequence. automobile transmission disassembly sequence planning method is put forward based on petri net,product subdisassembly part clustering and sequence optimizing is realized by using Petri-net related-matrix linear planning operation,which provides a new reliable method for automatically generating disassembly sequence plan.At last,the automobile transmission disassembly sequence plan analysis system is designed and developed,which is composed of product information exaction, disassembly sequence plan etc,the system is developed by using VC++6.0 and SolidWorks.It can support to build automobile transmission model,disassembly plan, generation,disassembly sequence plan optimization and so on.
