| description | Torsional vibration problem is one of the major technical problems of the industrial rotating machinery, especially, geared rotor system such as automatic transmissions from the view point of the transient response. This study aims at evaluating the effect of an ideal inerter on reducing the transient torsional vibration of the system as a preliminary feasibility study. Both resonance and anti-resonance frequencies of the torsional vibration system with an ideal inerter are analytically derived from the governing equation of the system. Under the simplification assumptions of the system parameters, moment of inertia and torsional stiffness, the numerical simulations for evaluating resonance and anti-resonance frequencies are performed. As the result, we find out that the ideal inerter have some effects of regulating resonance and anti-resonance characteristics, for example, reducing resonance and anti-resonance frequencies, generating new anti-resonance, adjusting both number and frequency of anti-resonance, and so on. These characteristics are depending on the system configurations, thus there are some resonance and anti-resonance frequencies unaffected or less affected by the inerter. In conclusion, the ideal inerter has possibility of reducing the transient torsional vibration of the system by adjusting the resonance and anti-resonance characteristics under the suitable parameter settings of the torsional vibration system. |
