Abstract

Using the Taguchi method, a 5-factorial, 3-level orthogonal array (L'18 (35)) was used as the experimental layout for 18 kinds of frictional lining specimen. These specimens were prepared in order to investigate their performance in establish a relationship between Ts/Td (Ts: static torque; Td: dynamic torque) and dμ /dνx (μ : friction coefficient; νx: relative velocity of frictional lining and clutch drum) parameters. The frictional torque and the rotational speeds of the driveline, clutch, and clutch drum as functions of contact time for 100 clutch cycles are experimentally obtained dμ /dνx and Ts/Td. In the study, a sharp rise in maximum contact pressure ratio occurred when the relative sliding velocity reached the critical velocity, Vc. This increase in maximum contact pressure ratio generally led to an increase of the (initially negative) dμ /dνx value. The mean values of dμ /dνx and Ts/Td for the clutching tests with 100 cycles can be roughly divided into three groups dependent on the fluctuation intensities of these two parameters, for each of which there is a linear relationship. The maximum contact pressure ratio significantly increases even increasing the mean value of dμ /dνx.
