Abstract

PURPOSE: To secure application of the tensile or compression load to the turning sample simultaneously with the twist torque by incorporating the direct-acting actuator into the power circulation type testing machine which gives the dynamic torque to the turning sample.
CONSTITUTION: Direct-acting actuator 23 is connected to one axle 8 connected directly to test sample 3' for the power circulation type testing machine which gives the dynamic twist torque to turning sample 3'. Actuator 23 is given the hydraulic pressure driving through application of the signal obtained by piling the dynamic load of dynamic load signal source 28 onto the reference load signal of reference load setter 27 to servo valve 30 via amplifier 29, and as a result axle 8 is stretched or compressed. The differential pressure signal detected by diferential pressure signal 26 is fed back to amplifier 29 to give the servo control to actuator 23. Accordingly, the tensile or compression load can be applied to sample 3' simultaneously with the dynamic twist torque by giving the simultaneous servo control to both actuators 18 and 23.
