Krushelnytskyi V. Justification the dynamic modes movement loadlifting cranes of bridge type

In the thesis are studies that are intended to reduce the dynamic increase in load metal tap while moving the crane by optimizing the transitional regime starter motor mechanism for moving the crane. A dynamic analysis of tap span displacement using two-, three- and fourmass dynamic and mathematical models. The basic causes of the dynamic loads that arise in the metal span crane. Optimized transition process start the electric mechanism for moving the crane to span three and fourmass dynamic model of the crane on various optimization criteria and analyzed the theoretical study of optimal control. The system of the drive mechanism for moving the crane span, which ensures the implementation of optimal control. To confirm the theoretical calculations matched measurement and filing equipment and conducted experimental research on bridge cranes. Based on the research results offered recommendations to develop control systems span crane, the use of which allows to reduce dynamic loads on the metal structure when moving the crane to a minimum.
