Abstract

In this paper, the design of a high-angle drive frame structure supporting a large load while considering the necessary variables such as hinge position and frame weight is presented; furthermore, the geometrical design variables are solved through geometric boundary conditions and optimal deflection equations. This study consists of two parts. First, the mathematical model of the deflection under the high load condition of the high-angle drive frame, boundary conditions, and design variables are selected, and the solution of the geometric deflection equation are then checked. The cross-section of the frame has a rectangular shape, and the deflection model is a two-point support simple beam model. The deflection equation and boundary condition equation of the high-angle drive frame are determined using the hinge position and frame length. Second, the validity of the deflection equation is verified through finite element analysis; further, it is verified whether the hinge position and frame length corresponding to the geometric solution satisfy the optimal deflection. The optimal geometrical design parameters for designing a high-angle driving frame structure that can withstand high loads are determined. Then the appropriateness of the optimal solution is demonstrated through structural analysis. Finally, the validity of the geometrical optimization method is verified.
