Electro-hydrostatic actuator with snubbing mechanism and control method using such an actuator |
摘要 |
<p>The present invention is to provide an electro hydrostatic actuator with a damping mechanism including a cylinder type actuator main body (1), a piston (2) having a piston rod, the piston slidingly moving in a cylinder of the actuator main body, a motor (18), a pump (19) for supplying fluid according to the rotation of the motor, a mechanism for adjusting a running amount of the fluid into and from the cylinder according to the motion of the piston, and a reservoir (8) for adjusting the supply of the fluid corresponding to a volume difference generated according to the motion of the piston, and a controller (17) which controls the number of revolutions of the motor according to the calculated load torque, and a damping control method used for this. An electro hydrostatic actuator of realizing a damping mechanism capable of increasing energy efficiency, when used for a landing gear retraction/extension device of an airplane, can be provided.</p> |
