Bridge crane emergency braking method for trolley stop and load swing eliminating

Provided is a bridge crane emergency braking method for trolley stop and load swing eliminating. The aim of emergency braking of a non-linear bridge crane system is achieved. The method has the performance of quick trolley braking and load swing inhibiting. Firstly, the target of crane system emergency braking is deeply analyzed and divided into two parts to be treated, namely, quick trolley braking and load swing inhibiting in the braking process. Then, corresponding control methods are designed aiming at trolley braking and load swing inhibiting through analysis of a system dynamics model. Finally, two control strategies are combined, a comprehensive emergency braking strategy is put forward to achieve the control target of trolley stop and load swing eliminating at the same time. The experiment result indicates that the method can achieve a good control effect, and has high actual application value.
