Kinematics Automatic Design of Planar Linkage Mechanism Based on Genetic Program

Abstract:

Given kinematics quantitative target and requirements to executive links of a planar linkage mechanism, regarded the distance between the point set of the quantitative target and the actual’s as a whole metrics approximate design requirements, and taken this metrics as kinematics design fitness function, according to multi-branch tree expression and random configuration method to create mechanical initial population made the mechanical population evolution towards the target requirements by the use of copy, crossover and mutation operators of genetic program. In the evolutionary process, inserted kinematics automatic analysis technique, design examples indicated that using a genetic program can search parallel in different mechanical configuration space and dimension space, automatically searched to such kinds of mechanisms approximate kinematics target and requirements, thus fulfilling the kinematics automatic design.
