For this reason, when resonance occurs at the lower natural frequency of the two natural frequencies as the rotational speed of the damper device 10 (frequency of vibration input to the damper device 10) increases, the second spring SP12 drives the resonance. The phase of vibration transmitted to the member 16 and the phase of vibration transmitted from the fourth spring SP22 to the driven member 16 are shifted. Accordingly, as shown in the present disclosure (solid line) and the comparative form (broken line) in FIG.
- the smaller of the two natural frequencies according to the increase in the rotational speed of the damper device 10 (the rotational speed of the intermediate transmission member Mm).
- the vibration in the driven member 16 becomes smaller.
- the vibration in the driven member 16 becomes sufficiently small (in the case of the comparative example, it becomes minimal).
- the rotational speed (frequency) of the damper device 10 in which the vibration in the driven member 16 becomes sufficiently small is referred to as anti-resonance rotational speed (frequency).
- the rotational speed of this anti-resonance is that under ideal conditions, the torque vibrations of the second and fourth springs SP12 and SP22 connected to the driven member 16 have the same amplitude and opposite phase, and as a result, torque fluctuations in the driven member 16 It means the rotational speed (frequency) of the damper device 10 that becomes zero.
- the inventors of the present invention obtain the anti-resonance frequency fa in the damper device 10 including the first to fourth springs SP11, SP12, SP21, SP22 and the intermediate transmission member Mm by various analyzes by the equation (2). I found.
- Expression (2) “J21” is the moment of inertia of the first intermediate member 12, “J22” is the moment of inertia of the second intermediate member 14, and “k1” is the drive member 11, the first intermediate member 12, and Are the combined spring constants (stiffness) of the plurality of first springs SP11 acting in parallel, and “k2” is a plurality of second springs acting in parallel between the first intermediate member 12 and the driven member 16
- the composite spring constant (rigidity) of SP12, “k3” is the composite spring constant (rigidity) of the plurality of third springs SP21 acting in parallel between the drive member 11 and the second intermediate member 14, and “k4” "Is the combined spring constant (rigidity) of the plurality of fourth springs
- the inventors of the present invention have two natural frequencies of the damper device 10 as a whole when the composite spring constants k1, k2, k3, k4 and the moments of inertia J21, J22 are constant values and the composite spring constant k5 is a variable. It has been found that the characteristics of the natural frequencies f21 and f22 on the small side and the large side and the anti-resonance frequency fa with respect to the combined spring constant k5 can be obtained as shown in FIG. As can be seen from FIG. 6, the natural frequency f21, the anti-resonance frequency fa, and the natural frequency f22 increase in this order from the lower frequency side, and all increase as the composite spring constant k5 increases. Yes.
- the two are separated from the anti-resonance rotational speed (the rotational speed corresponding to the frequency fa) as the rotational speed increases.
- the phase of vibration transmitted to the driven member 16 from the second spring SP12 approaches the rotational speed (large-side resonance rotational speed) corresponding to the higher natural frequency (natural frequency f22 in FIG. 6) of the natural frequencies.
- the deviation of the phase of the vibration transmitted from the fourth spring SP22 to the driven member 16 becomes smaller, and the vibration in the driven member 16 becomes larger.
- the rotational speed of the damper device 10 increases, the rigidity of the intermediate transmission member Mm (the combined spring constant k5 in Expression (2)) increases.
- the anti-resonance frequency fa increases. Therefore, as the rotational speed of the damper device 10 exceeds the rotational speed N1, the anti-resonance rotational speed (the rotational speed corresponding to the frequency fa) and the large-side resonant rotational speed are moved to the larger side (anti-resonant). From being separated from the rotational speed of the first side, and approaching the large-side resonance rotational speed).
- the rotational speed region of the damper device 10 that can exhibit good vibration damping performance can be expanded.
- the intermediate transmission member Mm is designed so that the combined spring constant k5 changes so that the current rotational speed of the damper device 10 becomes the anti-resonant rotational speed (the rotational speed corresponding to the frequency fa)
