Abstract : An examination is made of the problem of the movement of a solid with a rigid connection over a dry surface. The length of the connection is variable in time. The dependence of sliding friction on the velocity is nonlinear. Weak nonlinearity of the system is assumed. The force of static friction depends on the time of nonmoving contact. Equations are formulated for the segment relative to movement and rest. The equation relative to movement is solved by methods of successive approximations and by variable scaling. The condition of the existence of stops is presented. A determination is made of the period of vibrations with stops. The equation relative to movement for a concrete series of parameters is solved numerically using a digital computer and is compared with an analytical method. (Author)
