る。 The two flywheels 3 and 5 are elastically constrained to each other in the direction of rotation, and their rotational speed is
NA and NB are detected by electromagnetic pickups 9 and 10. Generally, the rotation speed of flywheels 3 and 5
NA, NB are engine 1 as shown in Figure 3.
For the average rotational speed N av, NA=N av +ΔNA,
NB=N av +ΔNB, which constantly changes, and a relative torsion angle occurs between both flywheels. The detected rotation speeds NA and NB of flywheels 3 and 5 are:
It is input to the subtracter 11, and the subtracter 11 converts NA and NB.
The difference between NA and NB is calculated. NA~NB=
Since ΔNA ~ ΔNB, the component of the average rotational speed N av of the engine 1 is eliminated, and both flywheels 3,
Only the difference in the rotational fluctuations of the two flywheels 3 and 5, that is, the fluctuation component of the relative torsion angle of both flywheels 3 and 5, is extracted as shown in FIG. The relative torsion angle corresponds to the amplitude of the relative vibration between both flywheels 3 and 5, so by calculating the rotation speed difference NA ~ NB, the variation in the amplitude of the relative vibration is independent of the absolute values of NA and NB. It is taken out. Therefore, the so-called S/N ratio (signal/noise ratio) increases, measurement accuracy increases, and the level of vibration between both flywheels 3 and 5 can be detected with high accuracy. The amplitude between both flywheels 3 and 5 becomes NA when approaching the resonance state.
Since NB is in an antiphase relationship, it becomes particularly large.

NB is input to the controller 12 as a signal representing the level of the vibration state of the flywheels 3 and 5, and is set in advance by the controller 12 and NA.
The peak value of ~NB, ie, the value of H in FIG. 4, is compared. As shown in Fig. 5, NA~NB is a small value (NA~NB) 2 when the engine 1 is at the normal idle speed N1 , but is large when the resonant speed N0 of the flywheels 3 and 5. Value (NA~NB) becomes 0 . The controller 12 has N 0
The vibration level of the flywheels 3 and 5 corresponding to the rotation speed N2 , which is a sign of resonance at a rotation speed between It is preset as . This rotational speed N2 is a rotational speed that can be easily restored to the original idle rotational speed N1 by increasing the amount of fuel. The controller 12 also has a resonance rotation speed.
The difference in rotational speeds (NA to NB) 0 is set as the vibration level of the flywheels 3 and 5 corresponding to N0 or a rotational speed close to it.

前に回避される。 When the level H of the rotational speed difference NA~NB inputted to the controller 12 from the subtractor 11 becomes greater than (NA~NB) 2 as the engine rotational speed decreases to N2 , it is a comparative judgment. and controller 1
The actuator 13 is actuated by the output 14 from 2, and the accelerator lever 16 of the injection pump 15 is activated.
is activated to increase the amount of fuel. accelerator lever 16
By this operation, the amount of fuel supplied from the injection nozzle 17 to the combustion chamber of the engine 1 is increased, and the rotational speed of the engine 1 is restored to the original idle rotational speed N1 .
When the rotational speed of the engine 1 reaches N1 , the actuator 13 is deactivated and the normal fuel supply amount is maintained again. In this way, when the vibrations of the flywheels 3 and 5 reach a certain level, this is detected and the engine speed is restored, preventing the engine 1 speed from dropping to the resonance speed N0 . Therefore, resonance of the flywheels 3 and 5 is avoided in advance.

れる。 On the other hand, even if the engine speed reaches N 2 and the amount of fuel is increased, for some reason the engine speed does not recover and drops to the resonance speed N 0 , when the relative torsion angle becomes (NA ~ NB) 0 . , the controller 12 determines that it is impossible to avoid the resonance of the flywheels 3 and 5, and the solenoid valve 18 of the injection pump 15 is operated in response to a command from the controller 12, the fuel supply is stopped, and the engine 1 is stopped. Ru. In addition, if the elastic member 4 is damaged for some reason during idling, both flywheels 3 and 5
Because the connection between the flywheels 3 and 5 is broken, both flywheels 3 and 5
The relative torsion angle between (NA~NB) becomes 0 or more.
If the elastic member 4 is damaged, the load on the engine 1 will be suddenly reduced, and there is a risk that the rotational speed of the engine 1 will become unnecessarily high and the engine will run out of control. In this case as well, it is determined that continued operation is impossible, and the engine 1 is stopped. By stopping the engine 1, runaway of the engine 1 and continued resonance of the flywheels 3 and 5 are prevented, and the engine 1 and its surroundings are appropriately protected.
