Abstract:
Self-lubricating bearings are the basic components of the aviation industry, and the precision forming process of bearings is one of the kernel technologies, which is urgent to be self-developed. A method called unconstrained surface directional rolling process was put forward, and then the flow chart of process optimization was designed. Based on the numerical analysis model of rolling process, Latin hypercube sampling method was used for the design-space analysis. By using BPF+NSGA-II and Kriging+PSO algorithms, the rolling process was simulated and optimized, and then the results were verified by experiments. Study shows that by the use of the new proposed process and the optimization methods, the products can get a higher quality; results of optimization and experiments are valid and consistent, comparing with BPF+NSGA-II algorithm, results of Kriging+PSO algorithm are slightly better.
