Modeling of dynamic loadings on a tower crane jib

Article describe processes of modeling of dynamic loadings on on a tower crane jib and represent their in analytic and, graphic kinds with using of modern computer technologies. Complexity of such tasks is concluded in depending these characteristics from load characteristics of the crane, weights and inertial parameters of elements of the mechanism of the lifting of loads, having a nonlinear appearance. The proposed procedures of modeling allow to reduce time and costs of such calculations at least in several hundred times and effectively to carry out researches in any usage mode and on all design stages of tower cranes, providing good visual presentation of received results
