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.

摘要翻译：要解决的问题：为了通过避免产生扭矩不足或分辨率不足，在进行负载试验或塑性变形处理时稳定负载波形。解决方案：弹性体11整合到通过伺服电动机的旋转而向前和向后移动的装载杆3中。弹性体11具有弹簧常数，其中最大负载频率变得高于对应于对象的负载负荷的规定频率，并且位移控制时间的有效分辨率满足规定的分辨率。位移计13测量弹性体11的位移，马达控制电路15基于弹性体11的位移来执行伺服马达的旋转的反馈控制。因此，即使当通过静载荷测试或通过静态加压处理大不相同，可以保证伺服电机能够显示足够的加载转矩的转速。此外，基于静态负荷试验或静态加压处理中的位移控制，也能够在电动油脂致动器1中进行稳定的负荷控制。版权所有（C）2006，JPO＆NCIPI
