Lightweight Design for Lower Beam of NC Isothermal Hydraulic Press

Abstract:

In order to satisfy the requirements of light weight and high stiffness for NC isothermal hydraulic press, a method of lightweight design for lower beam is proposed. Key geometric parameters of lower beam affecting mass and stiffness are extracted as design variables. Latin hypercube sampling is used to produce samples of design variables in order to explore relationship between stiffness, mass and design variables. Calculating data are processed with second order stepwise regression and regression equations for stiffness and mass are obtained. Mathematical model for lightweight design is established by regression equations. The goal of lightweight design is to decrease mass of lower beam while stiffness is set as constraint. When lightweight design is finished, the mass of lower beam is decreased by 11% and its stiffness remains unchanged.
