Specification optimization for three-roller planetary rolling

Due that the three-roller planetary rolling is a critical stage to produce copper alloy pipes, it is significant to optimize related specifications. In this regard, a method, which integrates orthogonal experiment design, BP neural networks and genetic algorithms, is developed for the optioning, mapping and optimization purposes. Afterwards, the optimal combination of specifications can be obtained. Therefore, this approach has revealed its reliability in practice by taking such advantages of multi-criteria testing via orthogonal experiment design, self-learning and adaptive nonlinear mapping and forecasting via neural networks, and natural selection and evolution via genetic algorithms.
