摘要
从起重机的可监测性、安全性和可靠性影响角度出发,选取强度、刚度、稳定性3个方面的健康指标,建立起重机结构健康指标评价体系。通过对起重机结构破坏形式的分析来阐述健康指标的选择原因,并对健康指标设定相应的监测标准,通过对监测数据的分析挖掘,得到各指标的健康评价值,从而实现对起重机整机的状态评价。
Starting from the monitor capability,safety and reliability of lifting equipment,a healthy index evaluation system is established,which includes the strength,the stiffness and the stability.The selection of healthy targets is coming from the analysis of failure form of the crane structure.The monitoring standard is set to the health indicators.Through the analysis of the monitoring data,we can get the healthy data of each index,so as to realize the state evaluation of the crane.The evaluation result for the bridge crane shows that it can enhance the structural reliability and safety of crane,and provide the theory basis for the structure health maintenance strategy.
