Opis: The paper addresses the importance of topology and shape optimisation on improving the performance of a device operating in a mine industry. The process of increasing the stiffness and the value of the first eigenfrequency of the load-carrying structure will be demonstrated. In order to satisfy both objectives simultaneously, two initial optimisation domain models were introduced. The first was the most commonly used optimisation model with full material, while the second was a model with an initial gyroid lattice structure in the optimisation domain. The results obtained by the optimisation of the load-carrying structure were used to analyse the effect of stiffness and eigenfrequency on the four-bar mechanism path of the coupler point and the reduction of the value of the joint forces of the most loaded links. 24 refs.
