Method for monitoring the output of an electromechanical actuator of the rotary-linear type |
摘要 |
<p>The invention relates to a method for monitoring the output of an electromechanical actuator of the rotary-linear type in order to detect a gradual seizing thereof, wherein said method comprises: measuring the intensity, representative of the motor torque, of the electrical current powering an induction winding of the actuator and the axial stress undergone by an actuator rod; calculating the ratio (axial stress undergone by an actuator rod/motor torque) representative of the global output of the actuator and of its present state; and generating an evaluation of the present condition of the actuator based on its present state and optionally on previous stored states and on outer parameters.</p> |
