Zaproponowano specjalną metodę pomiarów odchyleń geometrycznych parametrów głównych belek suwnicy. Przeprowadzono oszacowanie zmiany parametrów w stosunku...
The questions of parameter optimization for bridge crane main beams have been considered. Optimization criteria have been analyzed. The optimality criterion has been chosen as the p-value which characterizes the rigidity to the main beam mass ratio in the designed and the basic variants of the bridge crane of pre-set load-lifting capacity. The p-value must be maximal, it characterizes the frequency...
