<p><P>PROBLEM TO BE SOLVED: To provide fatigue testing equipment capable of performing an acceleration amplitude constant sweep test in a wide frequency band including a high frequency region. <P>SOLUTION: The fatigue testing equipment has an acceleration detection means for detecting the deformation speed of a workpiece and a control means for controlling a servomotor on the basis of the detection result of the acceleration detection means so that the ratio of the deformation speed and predetermined speed of the workpiece is received in a predetermined range regardless of a cycle for adding repeated load at each time when the cycle for adding the repeated load to the workpiece is changed. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
