Hazard Identification of Portal Crane In-use & Research on Its Application In a Shipbuilding Company

Abstract

Abstract Fatigue damage is always the main cause of the crane damage. The prediction method of fatigue life take far reaching impact on the design and service life of the crane. Therefore, it is extremely important to study the fatigue life prediction method of crane. In this paper, the existing fatigue life prediction methods are summarized systematically. And the fatigue life research was involved in metal material, mechanics, vibration mechanics, fatigue theory, fracture mechanics and so on, which made a difference between the predicted result and the actual life. The emergence and application of new technologies promote the development of the fatigue life evaluation methods, which could debase the risk of portal crane in use significantly.
