Application of topological optimisation in forming of cast cellular structures

Cellular structures are critical components which perform as energy absorbers in the defense, aerospace and automotive industries. Simultaneous application of topological optimisation algorithms for strength forming, solidification simulation software, additive manufacturing (AM) methods and solidification process control technologies may have a significant impact on building lightweight and strong structures. The shape of such structures is optimally adapted for transmission of loads with certain action of external forces and bearing methods. The purpose of this paper is to present the potential released by joint application of topological optimisation methods and AM methods in building of casting equipment for production of cellular castings which can resist compressive forces.
