Analysis of mathematical model of dynamics of lifting crane
Abstract
In paper have been carry out dynamic model of mechanism for cargo lifting. It is presented as few discrete masses, whitch connected with elastic constrains. On basis of dynamic model have been carry out simulation of lifting cargo dynamic. The mathematical model is multi- stage, in which each step is described by system of differential equations. In addition, initial and final conditions of masses movement are showed. Analisys of mathematical model have been cary out. The analysis of mathematical model, which showed that cable tension stage and lifting does not allow terminal conditions specified in advance motion of reduced masses crane bridge and load.
