Optimize Design of a Light Truck Frame

Abstract:

In this paper the basic structure of frame is optimized through homogenization method in the basic frame structure loaded with bending conditions under the conditions that ANSYS is regarded as the optimal design platform, the flexibility of frame is taken as the objective function and the volume is used as a constraint The optimization topology structure of the frame is obtained which meets the volume constraints and total compliance smallest. Using the ANSYS software calculates and verifies the security of frame structural strength under the fully loaded bending condition. Model and optimization methods used in this paper also can apply to other types of optimization design of the frame, and provides a useful reference for the optimized design of the similar structure.
