Dynamic Model and Dynamic Response of Automobile Dual-Mass Flywheel with Bifilar-Type Centrifugal Pendulum Vibration Absorber

Figure 2

Simplified model of the bifilar CPVA. O: rotary center of the secondary flywheel; A: equivalent connection point of the CPVA; M: center of mass of CPVA; α: rotation angle of the secondary flywheel; ϕ: the swing angle of the CPVA relative to the secondary flywheel; R: distance between the equivalent connecting point of the CPVA and the rotary center of secondary flywheel; l: distance from the equivalent connecting point of the CPVA to its centroid; F: centrifugal force of the CPVA; d: force arm of centrifugal force; r: distance from the centroid of the CPVA to point; m: mass of the bifilar CPVA.
