転アクチユエータを用いた交番荷重発生装置。[Scope of Claim for Utility Model Registration] (1) A hydraulic rotary actuator equipped with a double eccentric crank pin is provided in the rotary head, and this crank pin is connected to the supply side of the alternating load via a connecting rod. An alternating load generator using an eccentric hydraulic rotary actuator. (2) The rotary actuator has an outer cylinder that is installed on the drive shaft and rotates, an eccentric circular hydraulic chamber inside the outer cylinder, and is rotatably inserted into the hydraulic chamber so that the rotation angle is adjusted between the outer surface of the actuator and the hydraulic pressure chamber. It has an eccentric inner cylinder regulated by wings on the interior surface, and a crank pin protruding outward from the outer cylinder from the side eccentric from the center of rotation of the inner cylinder, and the hydraulic chamber is partitioned by the wings. An alternating load generating device using a double eccentric hydraulic rotary actuator as set forth in claim (1) of the registered utility model, wherein each separate chamber portion communicates with a hydraulic power source.
