The Use of Topology Optimization in Shaping the Strength of Castings

Abstract:

The article discusses some of the issues associated with the use of topology optimization in shaping of the strength of castings. This kind of optimization is performed in the preliminary design phase, when the shape of the constructed part is not yet defined. The limitations that apply to the designing process concern the dimensions, boundary conditions, loads, forces, and cooperation with other structural elements. Topology optimization determines the arrangement of the material in space, so that under the conditions of loads, exploitation, and the design assumptions, the construction will have smallest possible weight. The article presents a few methods of optimization and provides simple examples. The computer calculations were carried out based on, the Finite Element Method (the Abaqus software), and the authors’ subroutines optimization algorithm that uses the results obtained in FEM. The example of the method to optimize the shape of mine shaft tubing is presented. The verification of the casting technology was conducted in MAGMASoft, taking into account the influence of the topology optimization on the production possibilities.
