| Abstract |
The amplitude-frequency characteristic equations of a nonlinear vibroprotection system with an isochronous roller damper are obtained in the first approximation. On the basis of these equations, we carry out a numerical experiment and propose a numerical-graphical method for determining the optimal tuning parameters of such a damper. It is shown that the natural damper tuning frequency in the nonlinear setting does not coincide with the natural damper tuning frequency in the linear setting. Numerical analysis is also used to determine that the maximum amplitudes of the bearing body in the nonlinear problem exceed the maximum amplitudes of the bearing body in the linear problem. It is shown that the use of the new isochronous roller damper permits dramatically decreasing the forced vibration amplitudes of bearing bodies. |
