Fundamental criteria for the design of aircraft are low weight, high rigidity and high strength structures. As such, topology optimization (TO) is an attractive technique for the design of efficient structures. TO refines a designated design space subjected to a series of loads and restraints, numerically producing a structurally optimized solid part. Commonly the optimization objective is to minimize the strain energy of the structure given a specified mass. Yet, a serious challenge to the widespread adoption of TO is related to interpretation of the optimal topology and its manufacturing feasibility. The TO process often results in an organic looking structure with complex geometry that cannot be manufactured with contemporary methods. The goal of this research is to develop a Topology Optimization Results Spaceframe Interpreter (TORSI) to post process TO results into producible welded-tube spaceframes. The methodology of the TORSI consists of four steps: 1) Cubic Mesher – Converts commercial TO results into a binary cubic mesh, 2) Frame Extractor – Identifies a series of nodal junctions and the connecting members utilizing image processing techniques 3) Section Sizer – Identifies the cross-sectional dimensions of individual members within the spaceframe, 4) Part Modeler– Automatically creates a rendering of the spaceframe within a three dimensional CAD environment.
