摘要： PROBLEM TO BE SOLVED: To provide a non-contact follower device for the flaw detection of a pipe for allowing a flaw detection sensor to precisely follow a pipe rotated in a pheripheral direction at the time of flaw detection. SOLUTION: The follower device 100 is equipped with a non-contact displacement meter 2, a positioning means 3 for moving the flaw detection sensor 1 within the plane crossing the axial direction of a pipe P at a right angle and a positioning control means 4 for controlling the positioning means. The positioning control means estimates the time for the region of the pipe, of which the displacement is measured by the displacement meter on the basis of the positional relation of the displacement meter and the flaw detection sensor and the number of rotations of the pipe, to arrive at a predetermined position on the straight line by passing the center of rotation of the pipe to extend in a Z-axis direction and controls the positioning means on the basis of the displacement measured by the displacement meter and the operation delay time of the positioning means so that the relative position in the Z-axis direction of the flaw detection sensor with respect to the pipe after the elapse of the estimate time becomes almost constant to move the flaw detection sensor in the Z-axis direction. The positioning control means performs the same control even with respect to the X-axis direction. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To stabilize a load waveform by avoiding generation of torque shortage or resolution shortage, when performing a load test or a plastic deformation processing.
SOLUTION: An elastic body 11 is integrated into a loading rod 3 moving forward and backward by rotation of a servomotor. The elastic body 11 has a spring constant wherein the maximum loading frequency becomes higher than a prescribed frequency corresponding to a loading load to an object, and an effective resolution at the displacement control time satisfies a prescribed resolution. A displacement gage 13 measures displacement of the elastic body 11, and a motor control circuit 15 performs feedback control of the rotation of the servomotor based on the displacement of the elastic body 11. Hereby, even when a load domain loaded by a static load test or by a static pressurization processing is different greatly, a rotational frequency wherein the servomotor can show a sufficient torque in loading can be guaranteed. In addition, stable load control can be performed also in an electric-oil actuator 1 based on displacement control in the static load test or in the static pressurization processing.
