【Abstract】 Firstly,data standardization technology and combined classification method have been applied to carry out classification of motion behaviors and mechanisms in the mapping field between the motion behavior level and the mechanism level of conceptual design.The principle of computer coding and storing have been built to give a fast and broad selection of mechanisms that meets the requirements of basic motion characters.Then on the basis of mentioned above,the heuristic matching propagation principle(HMPP)of motion behaviors and its truth table serves as a guide to perform mechanism types selection.The knowledge base automatic reasoning system of mechanism motion scheme based on HMPP is developed.By means of depth first search strategy,the motion requirements are matched against objects in the knowledge base at different four levels of abstraction.Top down design process in this paper conforms to the law of innovative thinking for designers.If a direct match in higher level was not discovered,design course will be transformed into the match at low level automatically.According to the truth table of HMPP,once non zero elements in motion behavior ID("1"or"2")appear in the matching process,they will propagate until the solving process is over,and become one of the coding of the feasible solution.Heuristic nature of HMPP presents a top down solving method to decompose the complex requirements into several simpler ones.Differ from the traditional solving method,the method presented in our research work has two advantages,firstly it is easier to be operated and realized by a computer.Secondly,it is a creative process by nature.Finally an application is given to indicate its practicability and effectiveness.更多还原
