Optimization Design and Reliability Analysis of Remanufacturing Coating Structure for Eccentric Shaft

In order to solve the problem of optimization design and reliability analysis of eccentric shaft remanufacturing coating structure, the influence of design variable fluctuation on coating performance is considered based on response surface optimization. The Six Sigma Analysis (SSA) is introduced to improve the reliability of remanufacturing design schemes. Firstly, according to the sensitivity analysis, the optimization design variables of the structural optimization scheme are determined. Then, the full 2rd order polynomial response surface is established based on the experimental design data. With the Non-dominated Sorting Genetic Algorithm II (NSGAII) to solve the optimization problem, get a deterministic optimization scheme. Finally, the reliability of the deterministic optimization scheme is analyzed. The results show that the strength and stiffness of the eccentric shaft after remanufacturing still meet the design requirements, which provides a certain method reference and design reference for the eccentric shaft remanufacturing.
