PURPOSE:To facilitate the setting of the driving torque and the measurement of items at transmission points in a drive system by employing the torque control on a drive side and the speed control on a suction side thereof. CONSTITUTION:In the drawing, numeral 2 indicates a sample, 4 the speed detector on a drive side, 5 the speed detector on a suction side, 6 the torque detector on the drive side, 7 a torque reference value, 8 a torque arithmetic unit, 11 a speed reference value and 12 a speed arithmetic unit. After a certain torque is added on the drive side, as the speed on the suction side rises (lower), the rotational frequency on the drive side changes to that according to a shift position as in actual vehicle each time it reaches each of transmission points. Here, the control of the speed on the suction side enables the operation with a fixed speed at the transmission on the drive side depending on the relationship of the constant torque and the rotational frequency on the suction side to the mission ratio, if the speed reference value is fixed at the transmission point thereby facilitating individual measurements with a proper accuracy. The setting of the torque on the drive side can be changed easily by the opening of a throttle as in the actual vehicle. |
