Abstract
A rotational vibration testing device, including a rotating table, for testing both rotary shock and rotary vibration when used in conjunction with a pivoting shaker. The rotating table is mounted on a hub rotationally supported between two compression rings via tapered annular roller bearings preloaded in opposition. A motion arm connects to a radial arm on the side of the hub. The other end of the motion arm mounts to a height adjuster, which bolts to an electrodynamic shaker or other force generator. When the motion arm moves fore and aft, the linear acceleration is converted to rotational acceleration based on the radius from the stinger to the center of rotation. A nylon or equivalent median between the motion arm and the hub allows for sufficient flex without fore and aft play. The large tapered roller bearings preloaded in opposition eliminate z-axis acceleration and allow for greater payload testing.
