Abstract When determining the completion state of main cable a cableway bridge, although catenary theory can accurately consider nonlinear mechanical effect cable, iterative calculation is cumbersome and not convenient for engineering applications. Although based on parabola simple, accuracy long cables low. In this paper, considering avoiding calculation, fast algorithm wire rope bridge propos...

Topology optimization is an effective numerical tool to design high-performance, efficient and economical lightweight structures. The objectives of this work are threefold: development open-source large-scale three-dimensional topology framework, assessment uncertain loading on optimal validation engineering example. We introduce the cableway pylon problem [1] developing load case boundary cond...

This article presents an experimental approach to fatigue testing of cableway gondolas, carried out in accordance with the EN 13796-3 standard. Due limitations aforementioned regulations and lack clarity their content, when designing conducting tests there is a need find solutions that meet normative requirements, while ensuring cost-effectiveness tests. The work method loading, receiving degre...

The design of structures using topology optimization can improve the structural performance and save material, in turn reducing costs. Using a framework large-scale, three-dimensional implemented by authors an open-source multiphysical software, we investigate influence uncertain loading on optimized design. Direct differentiation is used to reveal relationship between displacements applied for...
