DYNAMICS OF FLEXIBLE ELEMENTS OF DRIVE SYSTEMS WITH VARIABLE CONTACT POINT TO THE PULLEYS

The developed technique makes possible to investigate the impact on oscillations of flexible elements of drive systems and transportation of nonlinear forces, the speed of longitudinal movement and perturbations of boundary conditions. Based on the obtained results it is proved that even for the linear analogue system the slowly time-dependent variable of the distance between the flexible elements (SE) contact points and the pulleys causes the change of the basic parameters of the waves. The limits of applying the wave theory of motion in the case of nonlinear oscillations of flexible elements of drive systems under slowly varying boundary conditions are expanded. The basic computations to analyze the main parameters of the dynamic process depending on motion speed of flexible element, tension force, and the ratio describing the motion principle of the contact point of flexible element and the pulley, are made.
