Safety Assessment Method of Bridge Crane Based on Cluster Analysis and Neural Network

Bridge crane is one of the most widely used hoisting equipments. The safety assessment of bridge crane can prevent potential failure in time. However, there is no comprehensive and accurate safety assessment method for bridge crane. This paper presents a safety assessment method of bridge crane based on cluster analysis and fuzzy neural network. First, we establish the safety assessment index system of bridge crane. Then, we revise the weight allocation of expert by cluster analysis, which can make expert evaluation set more rational. Next, we construct fuzzy membership function and the fuzzy neural network of safety evaluation model. Finally, this safety assessment method is verified by an engineering example, and the assessment result fits well with the actual situation.
