工艺条件约束下的再制造机电产品公差优化设计方法

摘要

To reduce the remanufacturing cost and improve product quality and processing stability of the remanufacturing of Waste Electromechanical Products (WEMP),an optimization method of remanufacturing tolerance for WEMP with process condition constraint was proposed.In this method,the characteristics of process condition constraint in tolerance design optimization for remanufacturing of WEMP were analyzed,and a four-level tolerance distribution system was constructed from tolerance design stage to manufacturing stage.Based on the design targets such as assembly accuracy and enterprise processing capability,a multi-objective optimization model of remanufacturing tolerance in design stage was established by taking production cost,quality loss,process capability in manufacture stage as the objectives.The modified method of the model was proposed based on the uncertainty precision to improve the rationality,and the Beetle Antennae Search Algorithm (BAS) was used to optimized the model.A used gearbox was taken as an example to illustrate the validity and practicality of the proposed method.The results showed that the proposed method was effective in optimization the remanufacturing tolerance of WEMP. ? 2023 CIMS.
