    Abstract: PURPOSE:To make it possible to impart an arbitrary nonlinear repeating load on various kinds of raw materials and primary-structure materials constantly by constituting a load actuator with a composite eccentric type direct motor- driven positioner which has a stage characterized by four degrees of freedom so that the driving can be controlled. CONSTITUTION:An output shaft is positioned at an original point. Under this state, a test piece 50 is inserted into an upper tightening device 5 and fixed. The lower end is fixed to a tightening device which is linked to a stage 31 through a universal joint 10. At this time, the output shaft 30 can be freely moved up and down. At this time, a signal for the precession of the output shaft is inputted into a composite eccentric type direct motor-driven positioner which is a load actuator. Then the output shaft performs twisting rotation thetaZ around the axis based on an output signal and also performs circular motion at a specified radius and at a specified speed within a two-dimensional plane. The motion close to the specified precession is repeatedly loaded on the test piece 50. During this period, six components of force acting on the device 5 are detected with a load cell 7.
