Micro dampers for prevention of un-commanded motion in mechanical feedback actuators
Abstract:
Apparatus for providing mechanical feedback of a position of an actuator to a controller in a high vibration environment. The apparatus includes a member that contacts a cam surface of the actuator such that movement of the actuator and cam surface causes the member to move. The apparatus also includes a spring that exerts a force on the member toward the cam surface to maintain contact between the member and the cam surface. The apparatus also includes a damper that dampens motion of the member, thereby eliminating resonant movement of the spring and member caused by vibrations.
