Performance Optimization of Forging Manipulator during the Whole Forging Stroke

摘要

The dynamic behavior of the forging manipulator during the whole forging stroke is investigated. The focus is on the dynamic force on the forging manipulator at the vertical direction. The effects of the resilient system parameters are studied, including the initial height of air chamber of the accumulator, the orifice area of the resilient cylinder. Results show that the dynamic force exerted to the clamp increases with the decreasing of initial height of air chamber of the accumulator and orifice area. On the other hand, the working efficiency of forging manipulator needs to be guaranteed. An approximately analytical relationship between working efficiency and resilient parameters is established by design of experiment (DOE) based response surface model. An optimization procedure by adaptive simulated annealing algorithm is executed. The goal of the optimization is to reduce the force transmitted to the clamp without losing working efficiency.
