Research on Assembly Sequence Optimization Classification Method of Remanufacturing Parts Based on Different Precision Levels

Aiming at resolving the problem of low assembly accuracy and difficulty guaranteeing quality remanufactured parts, an optimization classification method for sequence parts based on different levels is proposed. By studying characteristics recycled requirement that products not be lower than new products, selection matching constraints are determined, models with precision established. An algorithm combining particle swarm a genetic proposed to solve model obtain optimal sequence. Taking remanufacturing assembling 1.4 TGDI engine crank connecting rod mechanism as example, comparison data shows this can effectively improve qualified rate assembly, reduce cost after-sale claims, provide theories methods enterprises need hierarchical effective guidance development industry.
