Title:
LOAD TESTING DEVICE
Document Type and Number:
Japanese Patent JP2020176834
Kind Code:
A
Abstract:
To restrain the control of rotation speed from diverging when applying torque control to an input shaft and an output shaft of a test-piece.SOLUTION: A load testing device includes: a first device (10) having an input shaft motor (SM1), a first torque meter (TM1), and a first encoder (ENC1); a second device (20) having an output shaft motor (SM2), a second torque meter (TM2) and a second encoder (ENC2); and a controller that controls the torque of each motor based on the feedback value. The controller uses a common speed command value as the reference speed, generates a first torque command value from the ratio of a difference between the common speed command value and a first speed feedback value to the common speed command value, generates a second torque command value from the ratio of a difference between the common speed command value and a second speed feedback value to the common speed command value, and controls the torque of each motor.SELECTED DRAWING: Figure 1
