摘要： PROBLEM TO BE SOLVED: To control weight loading speed, while balancing two-point loading, in a four-point bending creep test. SOLUTION: A control device 100 controls each frequency set value of inverters 8, 9 based on a difference between two weights measured respectively by load cells 21, 22 in inverter frequency setting control, and the inverters 8, 9 control each operation speed of weighing devices 6, 7 respectively based on each frequency set value. The control device 100 performs displacement fixing control by using, as a control displacement, a displacement determined by subtracting a mean value of each displacement on two support points from a displacement on the center of a test body 1. The control device 100 can switch the displacement fixing control to/from weight fixing control. COPYRIGHT: (C)2009,JPO&INPIT
