起重机械金属结构振动与故障诊断的研究
摘要
Abstract
With the application such as the structural safety test for bridges and high-rise buildings and vibration fault analysis for rotating machinery,the vibration test technology has formed a complete system,including test principle and methods,processing and collecting of feature signals,fault diagnosis,and status identification.In terms of safety evaluation and estimation of in-service crane metal structure,through plenty of site vibration test data and results,it's found that the fatigue failure of metal structure is closely related to the vibration response.Therefore,the paper discusses feasibility of safety evaluation for metal structure of in-service hoisting machinery with the theory of vibration research and fault Diagno-sis,and also puts forward that mechanism research on vibration failure and vibration fault diagnosis are problems requiring urgent solutions currently.关键词
