Solution of Concurrent Tolerancing Optimization Design Model Based on Particle Swarm Optimization Algorithm

Firstly, a concurrent tolerance optimization design model was established. Minimum manufacturing cost was used as the optimization goal, and the assembly function requirement and machining capability were given as the restriction conditions of the model. Then, the particle swarm optimization toolbox （PSOt） was used to find out the solution to the concurrent tolerance optimization design model, and the detailed process was given. Finally, the optimization result for an example was given to illustrate the validity of the particle swarm optimization （PSO）based on PSOt. Compared with the existing result, the proposed method is better in solving non-convex programming problems.
