Hybrid Servo Actuator for Crash Test

摘要

Provided is a hybrid servo actuator for a crash test, and more particularly, a hybrid servo actuator for a crash test in which an operating part including a piston and a rod, a chamber supplying an air pressure to the operating part, and a controller controlling a movement of the operating part are integrally formed, thereby increasing a moving speed in a stroke direction of the operating part more than in a general hydraulic cylinder and pneumatic cylinder. The actuator includes an oil pressure cushion type cushion part provided therein to absorb a shock generated by a shock of an operating part even at the time of a malfunction of the operating part and discharge an oil pressure generated by the shock to the outside and thus is used semi-permanently.

主权项

1. A hybrid servo actuator for a test crash as a stroke driving actuator including a body and a means, comprising:
an operating part configured to include a piston which is provided to move in a hollow formed in a stroke direction inside the body and a rod which is connected to the piston to protrude in one direction of the body; a chamber configured to be formed at the other side of the body and supply an air pressure to the operating part; and a controller configured to be formed at one side of the body to enclose the hollow and control a movement of the operating part.
