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

Subharmonic centrifugal pendulum vibration absorbers allowing a rotational mobility

“…where 𝑛 𝑡 is the order of the pendulums' trajectory (called geometric tuning order in [45]) and 𝑥 [𝑘] , 𝛼 [𝑘] are trajectory and rotation coefficients. Note that in the case 𝑥 [𝑘] = 0, ∀𝑘, the pendulums' trajectories are epicycloids, which corresponds to the tautochronic trajectory for 𝜃 = 0 [25].…”

Dynamic stability of centrifugal pendulum vibration absorbers allowing a rotational mobility

“…X. Tan et al considered a CPVA made of a single pendulum obeying a non-linear rotation law and gave guidelines for the choice of this law [22]. E. R. Gomez et al investigated theoretically and experimentally the friction losses in a CPVA with rotating pendulums [23]. A new type of CPVA, made of a double pendulum, was studied by V. Manchi and C. Sujatha [24].…”

On the stability of pairs of subharmonic centrifugal pendulum vibration absorbers allowing a rotational mobility

“…However, recent studies demonstrated that using rocking pendulums can considerably improve the efficiency of CPVAs [35][36][37][38][39]. These works encouraged researchers to investigate the impacts of rotation [14,15,[40][41][42][43][44], including the authors of the present paper [16,17,30], who extended former results on the subharmonic solution by considering pendulums that can rotate relatively to the rotor.…”
