Rule-based method for generating mechanical kinematic function scheme

A rule-based generating method was put forward to improve the efficiency of mechanical kinematic function scheme design.The rules were set up according to the mechanism kinematic principles,and were classified into constructing rule and optimizing rule.Several spare new function schemes meeting design requirements could be created automatically with the constructing rules.And then,in order to reduce the number of spare function schemes,and to improve the decision-making efficiency,better schemes with higher priority were selected from the spare schemes using the optimizing rules.Application to the mechanical product design shows that the method can improve the engineering design efficiency and obtain more creative function scheme.
