Vibrodiagnostics express method of dry friction force at forced oscillations of dynamic systems

In article the express method of operative vibrodiagnostics the dry friction force is considered at forced oscillations of the dynamic systems, based on jump definition of vibroacceleration on vibrogramm, caused by abrupt change of dry friction force at change of movement direction. Procedure of quantitative identification of dry friction force invariant to operating forces of viscous resistance at their possible joint action, is characterized by high efficiency and productivity, and also simplicity of hardware realization.
