Research and Application of Topology Optimisation Design of Truss Structures

Truss structure is a common structural form. The optimal design of truss structure has important research significance. The main purpose of this paper is to discuss the method and practice of optimal design of truss structure in order to improve the efficiency and economy of structure. This paper introduces the basic concept of truss structure optimization design, and three types optimization design methods including shape optimization, size optimization and topology optimization. Then the topology optimization design is focused on in this paper. Firstly, the solid isotropic material point method in topology optimization is introduced. Then, combined with a practical engineering case, the application of topology optimization design in truss structure is analyzed and studied. The results show that the optimized truss design has good application effect in practical engineering. By considering the structural performance, cost and environmental impact, a more efficient, economical and environmentally friendly truss structure design can be achieved.
