Abstract
This paper presents a methodology to design optimal forming process parameters of the sleeper fixed reinforcing plate based on the use of computer aided engineering (CAE) technology. The methodology uses Unigraphics software to establish the numerical model and DYNAFORM software to simulate its sheet forming process to determine the feasible process parameters affecting its manufacturability, including whether the mould requires the binder, binder force, friction coefficient, and die fillet radius. The forming limit diagram and the thickness distribution diagram are selected to appraise and analyze the forming results. The orthogonal experiment method is adopted to simulate the design parameters to find out the optimum values for mould design.
