| Abstract: | Considering to wer crane load moving and oscillation characteristics,this paper sets up a polar coordinate system and a spherical coordinate system featuring a non-inertial refeernce frame.The non-linear mathematical model of load oscillation is built based on the general form of Lagrangian equation.The equilibrium is found.The linearized model around the equilibrium is derive.The dynamic behavior of load oscillation is simulated under all kinds of operation conditions. |
