Abstract
A measuring device is applied to an active damping system, the active damping system including a damper having a plurality of sensors and a plurality of actuators, the damper being arranged on an object to be subjected to damping. The measuring device includes: a transmission characteristic storage unit configured to store a plurality of transmission characteristics calculated from driving signals and vibration state signals; a damping performance setting unit configured to set damping performance including the amount of vibration reduction required of the active damping system and a frequency of vibration; and a damper configuration calculator configured to calculate how many the number of the sensors and actuators for the damper is increased or decreased on the basis of the transmission characteristics and the damping performance, with the increase or decrease being necessary in order that the damping performance set in the damping performance setting unit is satisfied.
