碩士 === 國立中央大學 === 機械工程學系 === 107 === An FEM model of rotary forging with double symmetry rolls of a spiral bevel gear is developed under the DEFORM-3D software. To observe the influence of work-piece geometry parameters and rotary forging process parameters to the forging maximum load and die-filling rate. Also, intend to find the rotary forging condition for optimum design. The four factors in the design include the work-piece geometry parameters, such as bottom inclination angle ß and bottom diameter D, and rotary forging process parameters, such as rotation of the upper die n_2 and feed amount of per revolution S. The experiment adopts 25 groups of analogs with the Box-Behnken design. Using the Minitab software to do the regression analysis and develop the prediction equations. Obtaining the optimum design of the forging maximum load and die-filling rate by using response surface methodology. Through the results of FEM simulations to verify the prediction equations with considerable accuracy.
