    • 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,
