Reliability-based robust design for kinematic accuracy of planar path linkage based on multi-objective optimization
A multi size probability synthesis method is proposed for the kinematic design of planar linkage with joint clearances and dimension tolerances.Minimizing the maximum failure probability of the output performance of the mechanism motion as the objective function,And reliability and motion continuity are used as performance probability constraints,Then established the reliability-based robust optimization design model of motion reliablity.While the given input and output relation of the motion were satisfied,the design parameters such as the length and the manufacture tolerances of the links are optimized.The results show that the theoretical model established in this paper is effective and feasible.Aiming at the design requirements,Based on the change characteristics of the failure probability and mean value in the whole region,the best scheme is reasonably selected according to the different weights of specific discrete point interval motion accuracy.
