The main results of the calculations of damped oscillations ofmanometric tubular springs (MTS) considering the hard tip are presented. The calculations are based on previously developed mathematical model. An assessment of the impact of the MTS mass on damped oscillation parameters (frequency and oscillation damping parameter) was made, the change of the limit value of viscosity of the damping fluid at which the aperiodic motion begins, as well as the value of the tip mass at which the system ceases to oscillate.

The paper presents the vibration analysis of 'modification' of a cultivator representing a manometric tubular spring (MTS) taking into account the rigid tip. It also considers the mathematical model of damped vibrations. The MTS dynamic model represents a thin-walled curved bar making in-plane vibrations within the central axis curvature. The MTS vibration equations are obtained according to the D'Alembert principle in projections on a normal and on a tangential component. The Bubnov-Galerkin method is used to solve the obtained equations.
