Abstract. Structural Topology Optimisation (STO) is a prevalent optimisation technique used nowadays to reach highly complex and efficient designs (weight-to-stiffness ratio) unable to achieve otherwise. Additive Manufacturing (AM) is a developing manufacturing process which overcomes many of the manufacturing limitations and realises highly optimised products through a layer-based fabrication process. Recent research on reticulated structures proposed using STO and 3D printing to design and fabricate alternative bespoke complex connection designs which have shown its significance through obtaining substantial weight reductions for the same structural capacity. This paper builds on previous research through optimising a single-layer S355 traditional node-connection under four loading cases, producing a state-of-the-art optimised connection design capable of withstanding the four loading cases considered and comparing the results to the traditional ones. In all loading cases, optimised shapes with 46.90% weight reduction were obtained with varying stress levels. A selection of the highly bespoke designs were 3D printed as a proof of concept for the applicability of AM.

<p class="p1">Light weight design of an articulating beam that is utilised for erection mechanism of heavy article (above 15-ton class) is quite challenging task considering high stiffness requirement at erection start mode. The research work presents structural topology optimisation of an articulating beam to obtain optimal material distribution within available space pertaining to required stiffness parameters and boundary constrains. Optimal weight of articulating beam structure is achieved using density optimisation technique aiming minimum compliance and volume. This study highlights problem formulation with solid isotropic material with penalisation optimisation technique with case study followed by discussion on various fabrication aspects for converting the topology results in to feasible design. As an outcome, optimal material design of the articulated beam is achieved that is converted into two feasible light weight designs considering manufacturing aspects. These designs are then validated for their structural adequacy with finite element analysis computing desired stiffness and strength parameters.<span class="Apple-converted-space"> </span></p>
