Patent attributes
Outer arm constrained layer dampers to improve actuator dynamics are disclosed. One embodiment provides a housing and disk pack mounted to the housing and having a plurality of disks that are rotatable relative to the housing. In addition, an actuator is coupled to the housing, the actuator having a plurality of suspensions arms for reaching over the plurality of disks. A first damper is coupled with an outside (or inside) portion of a top outside suspension arm of the plurality of suspensions arms. In addition, a second damper is coupled with an outside (or inside) portion of a bottom suspension arm of the plurality of suspensions arms. In so doing, vibration modes involving deformation of the top suspension arm and the bottom suspension arm are damped.
