In the work presented of physical model of the system with joint elastic strip in the rigid clamp. Nonlinear friction model contact between elastic strip and rigid clamp, taking structural friction into account is presented. During load, relieve and again load free part of the strip, displacement in a function of the longitudinal force external was determined. The obtained dependences of the displacement enable determination of the hysteresis loop describes elasto-frictional properties of the joint. The mathematical model of vibrating system with an elastic strip in a rigid clamp was built. The equation of motion for the nonlinear system were solved numerically and its damping characteristics were investigation.
