    • The vibrating device is configured to vibrate at a frequency that corresponds to a desired vibration frequency to be damped of the primary system (120, 220), such as a barring frequency, so that the vibrations in question can be controlled with delayed resonator -based control circuits for damping roll vibration of a fibrous web machine. Roll vibration can thus be significantly damped in the primary system of a fibrous web machine. The roll vibration reduction can be automatic or self-adjusting, and thus manual control is not necessarily required. Furthermore, relatively accurate roll vibration reduction is possible, i.e. the frequency of the so-called counter vibrator accurately compensates the harmful vibration of the actual primary vibrator,
    • 振动装置被配置为以对应于待主要系统(120,220)阻尼的期望振动频率(例如限制频率)的频率振动,使得所讨论的振动可以基于延迟谐振器 纤维网机的阻尼辊振动控制电路。 因此,在纤维幅材机的主要系统中,滚动振动因此可以被显着地减弱。 滚动减振可以是自动的或自动调节的,因此不一定需要手动控制。 此外,相对精确的滚动振动降低是可能的,即所谓的反振动器的频率可以准确地补偿实际主振动器的有害振动,

    • The present invention relates to a fiber web machine roll support arrangement (10), comprising a roll and a bearing housing (16) at both ends of the roll, the bearing housing (16) comprising a securing arrangement (22) through which the roll may be supported on the frame or the foundation (18) of the fiber web machine, where the bearing housing securing arrangement (22) comprises a vibration damping arrangement (20) provided between the bearing housing and the frame or the foundation of the fiber web machine. Said damping arrangement (20) comprising at least two damping zones (20.1, 20.2) having properties which are different from each other at least in that respect that they have different loss coefficients, and of said at least two different damping zones, the impact of the second damping zone on the total rigidity of the vibration damping arrangement is at frequencies ≤ 0,1 Hz greater than that of the first zone, and at frequencies ≥ 5 Hz, the impact of the first zone on the total rigidity of the vibration damping arrangement is greater than the impact of the second zone. The invention also relates to a partial roll winder utilizing the roll support arrangement.
