Aiming at the problems of low assembly accuracy,high comprehensive cost and difficult to guarantee the quality of re-manufactured products in the process of remanufacturing and assembly,an optimal matching method of remanufactured me-chanical products considering assembly accuracy and cost is proposed.Establish the quality loss function and comprehensive cost objective function of remanufactured parts,determine the dimensional chain constraints of assembly accuracy,and take the mini-mum comprehensive performance of the two objective functions as the optimization objective to build a multi-objective optimization matching model of remanufactured mechanical products,and PSO-GA hybrid algorithm is adopted to solve the multi-objective model.Finally,taking the remanufacturing and matching of crank connecting rod mechanism of 1.4TGDI engine as an ex-ample,the effectiveness and practicability of this method are verified.The multi-objective matching model proposed in this study can effectively ensure the assembly accuracy of remanufactured products,obtain the assembly sequence with the least comprehen-sive cost,make full use of remanufactured parts and improve the success rate of remanufacturing matching.
