Dynamic stability of centrifugal pendulum vibration absorbers allowing a rotational mobility

V. Mahe et al.

Summary: This paper investigates the dynamic stability of a new class of centrifugal pendulum vibration absorbers with mass rotation relative to the rotor. The efficiency of these devices depends on the synchronous motion of the oscillating masses, but can be compromised for energy localization, leading to a loss of mitigation performance.

Torsional vibrations in heavy-truck powertrains with flywheel attached centrifugal pendulum vibration absorbers

Erik R. Gomez et al.

Summary: A study on the application of a nonlinear centrifugal pendulum vibration absorber with normal-force dependant friction loss in a downspeeded powertrain of a heavy-truck is conducted. The performance of the CPVA is affected by system dynamics, and downspeeding of the engine can reduce CO2 emissions but increase torsional vibration and noise, which can be mitigated by using CPVA.

Effective and robust rocking centrifugal pendulum vibration absorbers

Johannes Mayet et al.

Summary: This work presents a design methodology for robust and effective centrifugal pendulum absorbers, which can translate the relative center of mass along a given path and rotate angular body. The method reduces rotor fluctuations and is suitable for aircraft and automotive drive systems. The application of nonlinear tautochronic design philosophy and nonlinear detuning enables the design of more effective and robust absorbers.

Normal-force dependant friction in centrifugal pendulum vibration absorbers: Simulation and experimental investigations

Erik R. Gomez et al.

Summary: A model of the normal-force dependant friction loss between the rotor and pendula is developed for bifilar centrifugal pendulum vibration absorbers (CPVAs). Simulation and order-response simulations with the proposed friction model show improved accuracy in predicting rotor oscillation amplitude. The developed experimental setup proves to be effective in validating the model parameters without the need for special test apparatus.

Study of dynamics of rotational centrifugal pendulum vibration absorbers based on tautochronic design

Xiaodong Tan et al.

Summary: This study proposed a method for designing key parameters of rotational centrifugal pendulum vibration absorbers. It found that the linear rotational CPVA had better damping effect than the nonlinear rotational and non-rotational CPVAs, and could reduce the impact on the rotor.
