Topological optimization of a crane jib
Machara, Marcel ; Pokorný, Přemysl (referee) ; Zeizinger, Lukáš (advisor)
This bachelor's thesis deals with the issue of topology optimization in the design of structures and machine parts. The first part of the thesis consists of a theoretical summary of the current state of knowledge of crane jibs and their basic categorization. The second part consists of theoretical knowledge about optimization problems and the method of topology optimization. In the third part, an example of the implementation of topology optimization on a cantilever crane is processed using the Ansys Workbench software. The parameters of optimized jib designs are compared with the parameters of their basic models. At the end of this chapter, an evaluation of the results of topology optimization is performed.
