Abstract

Abstract

A dynamic measurement method is used to conduct a real-time monitoring of a crane beam, collect great amount of strain-time diagram and deflection-time diagram in actual use and identify the modal parameters.This measurement and the result by the analysis provide certain evidence of the study of vibration and fatigue character of the crane beam, of the drawing up of crane beam load effect spectrum, and of the safety monitoring of the crane beam.
