| description | Dynamic loads regularities in elastic elements of the load-lifting machines were analyzed, in conditions of actual use they should be minimized.
An updated analysis of dynamic loads in crane ropes was conducted and conditions of loads minimization were determined.
Modes of load movement on elastic rope of lifting crane were substantiated. In these modes dynamic factor Kd minimizes and drive mechanism performs optimum movements. At the same time methods of classical variational calculus and apparatus of differential equations (ordinary) were used, and the calculations were carried out for two classic ways of load lifting ("hanging" and "with pickup").
The updated dynamic analysis was conducted and loads that arise in elastic elements (ropes) of lifting equipment were minimized within the two-mass model. At the same time methods of load lifting "hanging" and "with pickup" were considered for various possible modes of drive mechanism motion in the starting area.
Models for load lifting "hanging" and "with pickup" which minimizes the dynamic loads in the rope of the crane in its launching period were justified.
The results obtained can later be used to update and improve existing engineering methods for movement mode`s calculation of lifting cranes and their components (when lifting is "hanging" or "with pickup"), these modes minimize the rope load at optimal modes of drive motion as at the design (construction) stage of such systems, as well during their real operation. |
