Аналіз динамічних процесів стрілових кранів

Abstract

Research methods of the boom system dynamic processes of the crane with three degrees of freedom is described. The mathematical model includes the differential equations of motion of the load, the rotary mechanism with the boom and the drums. These equations form a system represented by Cauchy form and solved by numerical methods. The results of mathematical modelling of dynamic processes are analysed. Graphical dependences of motion parameters in time of the considered moving elements of the crane and cargo are constructed. Rational modes of start-up and exploitation of the truck -mounted crane example are substantiated.
