Kinematic scheme design based on design catalogue

First of all the essential procedure of design catalogue is expatriated on. And the methods of function coding and mechanism coding are defined according to the features of function and mechanism. On this base, the function table and mechanism table including evaluation criteria are constructed. Then because different users have different interests in the importance of various evaluation criteria of function, a user´s function table is set up to describe the user´s function on one hand and the different authority of each evaluation criteria for different functions is acquired with AHP(analysis of hierarchy process) on the other hand. In addition the user´s functions may be searched in mechanism solution table and the set of feasible solutions is obtained. At last the optimal solution is achieved with a fuzzy evaluation method. In terms of idea expressed above the software system kinematic based design catalogue is developed for kinematic design. Accordingly, a software system kinematic based on design catalogue is developed
