Method of monitoring a number of identical electromechanical, pneumatic or hydraulic actuators of a common operational assembly

摘要

Method entails operating the actuators in similar powering conditions, measuring the energy flux during the excitation cycle for each one, determination of a time-based curve of the measured flux and superposing (T) all of the individual curves (c). From the superposition a normality curve is determined which is used to trouble shoot any variations from it for individual curves.- DETAILED DESCRIPTION - An INDEPENDENT CLAIM is made for a device for executing the procedure
