Frictional self-excited oscillations

As explained in Chapter 6 the maximum friction F+ depends on the rate of tangential loading f at the break-down and decreases as this rate increases. The existence of this dependence causes a jump of the force of friction F+ - F c at the instant of break-down and thus results in a hard excitation of the frictional self-excited oscillations. Besides, a ”traditional” falling characteristic of the force of sliding friction F c as a function of the sliding velocity ẋ leads to a soft excitation of the system. The present Chapter is concerned with the analysis of frictional self-excited oscillations by means of the two dependences F+(f) and F c (ẋ).
