Optimization start hoisting machines by the criterion of minimum power density
Within the scope of the Braude –Ter-Mkhitarov generalized model of the load calculation of the load lifting machines’ mechanisms, the dynamic mode optimization of their start up regimes based on the minimal power criteria is proved in the article. In order to define the basic kinematic characteristics of motion of the mentioned mechanisms during transitional processes (start up/braking) and types of the arising oscillations (periodical, a-periodical, dynamic chaos) the method of a classical phase portrait as well as phase portraits of high orders is used.
