Research Status of Swivel Bearing and Review of Force-measuring Bearings Application
摘要
Abstract
Through the analysis of the conventional rotor system technology,the current research status in the aspects of structure form,material,stress state,weighing test and so on are summarized in this paper.Aiming at the limita-tion of single function,a new type of intelligent force-measuring bearing is introduced based on a project of a cross Longhai railway bridge.The new support integrates the stress sensor and other equipment into the conventional ro-tary support,with the functions of real-time monitoring of the internal stress state,remote data transmission and stress abnormal alarm.However,the new support still has some limitations,including the low degree of functional integration,unable to monitor the stress state at the position of the support foot.The research results provide a new idea for the further development of the rotary bridge in future,and also have a certain reference and reference sig-nificance for intensive study of force measuring bearings.关键词
