The transient phenomena of the driven shaft torque transmitted from the driving shaft through the dry friction clutch are studied theretically and experimentally using a model of clutch and the analog computer. Substantial agreements are found between the theoretical results and experimental observations. Results obtained are as follows ; The characteristics of friction on the slip surfaces of the clutch has a considerable effect on the time rate of increase of the driven shaft torque. An increasing friction force with an increasing relative speed between in-and output plates of clutch depresses the increase rate of the driven shaft torque and causes the retardation of the engaging time and an increase in the amplitude of the torsional vibration of driven shaft with an increase of the initial speed of the input plate of the clutch. With the same pressure on the plates of clutch, the excitation, the sustenance and the damping of the torsional vibration of the driven shaft depend on the initial speed of the input plate of the clutch.
