Aplikace metody topologické optimalizace při návrhu jistícího prvku

Abstract

The dissertation thesis deals with preparing a methodology for topology optimization applied to the design of the climbing belay element. The methodology is applied to cams of spring-loaded camming devices. The camming devices protect mountaineers in case of fall. The methodology consists of three pillars. The first pillar describes the importance of effective modelling for performing topology optimization. The thesis emphasises finding suitable optimization formulation for obtaining quality results. The thesis highlights the significance of complex problem analysis and preparation of the concept of overall optimization. Concept in general cannot be used for optimization due to complexity. However, optimization can be appropriately reduced. The reductions lead to solving time acceleration opening the possibility of finding a suitable formulation. The second pillar deals with the post-processing of topology optimization results. Results are usually not acceptable for direct use and require additional work. The thesis describes possible ways of smoothing geometries. The thesis proposes also metrics to help users with an evaluation of smoothing. The third pillar deals with the validation of new designs. Validation can be done using numerical modelling or experiments. Obtaining a new shape of cams is solving industrial needs, namely, it is a new lightweight shape that withholds the load-bearing capacity defined by the standard. The final proposed methodology is prepared in general, therefore, it is applicable on various industrial problems.
