为提高复杂机械产品再制造质量可靠性与稳定性,提出了基于装配偏差度的复杂机械产品再制造过程质量优化方法。综合考虑再制造过程装配偏差的形成原因及传递机制,构建了再制造过程装配偏差度函数。通过对相关质量控制域的划分,描述了基于装配偏差度的再制造质量优化判断条件及方法,并用模拟退火遗传算法求解装配偏差度在线优化模型,实现了对复杂机械产品再制造装配质量的优化。最后以某型主减速器主锥再制造总成装配过程为例验证了该方法的可行性和有效性。

Remanufacturing Quality Optimization Method of Complex Mechanical Products Based on Assembly Deviation Degree

In order to improve reliability and stability of remanufacturing quality for complex mechanical products, a remanufacturing quality optimization method of complex mechanical products was presented based on the assembly deviation degree. Considering the reassembly process variation and transmission mechanism, a reassembly process deviation function was set up. By dividing the relevant quality control domain, the conditions and methods of remanufacturing quality were described based on the assembly deviation degree, and the simulated annealing genetic algorithm was used to solve the assembly deviation degree on-line optimization model. Finally, the reassembly process of main gear demonstrates the feasibility and effectiveness.
