ELECTRICALLY ASSISTED SAFING OF A LINEAR ACTUATOR TO PROVIDE SHOCK TOLERANCE |
摘要 |
Electrically assisted safing of a solenoid linear actuator to provide shock tolerance is provided for a solenoid actuator, the actuator having an armature and at least one electromagnetic inductive coil. A controller, receiving an output from a motion sensor, adjusts an electrical power input to the electromagnetic inductive coil. When the output of the motion sensor indicates onset of an environmental transient exceeding a predetermined threshold of intensity, the controller adjusts the electrical power input such that an electromagnetic field generated by the coil is sufficient to restrain the armature in a desired position during the environmental transient. |
