摘　　要：基于安装在绞车刹车带上的光纤光栅应变传感器,对液压驱动绞车马达进行加载,试验得出光纤光栅应变传感器的应变差与液压马达压差之间的数学关系。试验结果表明:光纤光栅应变传感器的应变差与液压马达压差呈现线性关系。该结论可应用于各类液压驱动绞车缆绳张力的监测。Based on the Fiber Bragg Grating(FBG)strain sensor installed on the winch brake belt,the mathematical relationship between the strain difference of the FBG strain sensor and the pressure difference of the hydraulic motor is obtained by loading the hydraulic winch motor.The test results show that it is a linear relationship between the strain difference of FBG strain sensor and the pressure difference of hydraulic motor.The conclusion can be used to monitor the cable tension of all kinds of hydraulic winch.
