Abstract:
A system for announcing failure of a mechanically actuated arrangement employs a first coupler arrangement that couples an actuator to a structural element that is desired to be controlled, and a first force sensor is coupled to the first coupler arrangement. The first coupler arrangement and the first force sensor constitute a primary load path. Similarly, a second coupler arrangement is coupled to the actuator to the structural element and constitutes a secondary load path. Changes in the forces experienced by one or both of first and second force sensors are monitored by a controller/monitor system. A connector has a screw shaft in the primary load path and a preloaded tie rod in the secondary load path. Axial forces are generated by a drive motor, which can include a ball screw arrangement. Operating impulses generated by the ball screw arrangement are monitored during a predetermined interval of operation.
