MEASUREMENT METHOD OF DYNAMIC TORQUE

摘要

PROBLEM TO BE SOLVED: To provide a measurement method of a dynamic torque capable of remeasuring the dynamic torque by a suitable method when sliding of a main rope occurs.;SOLUTION: A distance that a car 1 moving at a first speed moves until stopping after reaching a first position is calculated based on an output signal from an encoder 9. Further, a distance that the car 1 moves in a first direction is calculated based on the output signal from the encoder while the car is moved in the first direction and stopped at a second position. When the sum of the calculated distances is shorter than a first reference distance, the car is moved in the first direction at a second speed which is slower than the first speed so as to pass through the first position again. Then, a distance that the car 1 moves until stopping after reaching the first position at the second speed is calculated based on the output signal from the encoder 9.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
