Longitudinal vibrations of a cylindrical bar from the action of harmonic forces

The longitudinal vibration of a cylindrical rod has been studied in an elastic medium from the action axial harmonic forces state compression tension. consideration took into account damping according to theory E.S. Sorokin. Taking account, internal friction made it possible approach real as source wave radiation. amplitude-frequency characteristic structure is built, taking changes parameters environment and rod. possibilities emergence resonance are established. At same time, cases were considered with without inelastic properties material. analysis influence on amplitude displacement latter carried out.
