Optimal mechanical design of single span screw feeders

Journal Article


Abstract


  • The mechanical design optimization of a typical screw feeder is described. The mathematical model of the optimization problem is established. The specific objective function is a combination of weight and deflection minimization and discharge per revolution maximization. The constraint conditions include flow property requirements and geometrical limitations. The important property constraints are the deflection with the effect of the screw flight considered and shaft strength considerations. The random search method is then introduced as the optimization strategy. Optimization results are presented for 32 different situations corresponding to different screw flight thickness and heights. For the optimal designs, the critical speeds are checked and the bearing selection method is introduced. From this particular optimization problem, conclusions are drawn which will provide sound guidance for the design of these significant materials handling units. (A)
