Topology Optimization of a Cableway Pylon with Assessment of Uncertain Loading

Topology optimization is an effective numerical tool to design high-performance, efficient and economical lightweight structures. The objectives of this work are threefold: development of an open-source large-scale three-dimensional topology optimization framework, assessment of uncertain loading on optimal topology and validation on large-scale engineering example. We introduce the cableway pylon design problem [1] developing the load case and boundary conditions supported by data based on an existing structure and provided by an industry partner. The resulting lattice-truss-like topology agrees with the loading conditions and model characteristics. The effects of uncertain loading on the optimal compliance is investigated per [2].     «
