Study On Polar Crane Dynamics Of Nuclear Power Plant

To develop nuclear power is a very important strategic measure in appeasing power demand, optimizing energy resource structure, insuring security of energy, acceleratimg sustained development of economy. Nuclear power is a kind of green energy resouece. Its technology is very mature and safe now. And it becomes a necessary component of our county's energy resource.With the construction of nuclear power station, its necessary facility, polar crane is laid on more attention. What the nuclear power plant's demand on the polar crane is heavyload, precise, and safe. So we demand that the crane should have more advanced characteristics of dynamics than before. In fact, the polar crane is not often used in nuclear power plant. But nuclear power enterprise found that the abrasion between guidewheel and rail is grave, which is owing to big transverse force between them. And this will increase the maintenance cost for the enterprise, debase the safety of the crane, demage the life-span of the crane.Firstly, this paper constructed a dynamic model of polar crane according...
