Determination of Vibration Parameters in Moderate& Damped Systems
نویسنده
چکیده
The undamped naturalfrequency CO, and the damping ratio [ can be determined from a plot of the jiee motion of the system. If the damping is light, ( < 0.2, the lqqarithmic decrement can be used to determine the coeficients. Systems with moderate damping are those in the range 0.2 < ( -C 1.2. A methodfor determining vibration parameters for systems with moderate damping is presented here. The method is easy to apply and while it is approximate, it is extremely accurate throughout the entire range of moderate damping.

متن کاملModel independent control of lightly damped noise/vibration systems.
Feedforward control is a popular strategy of active noise/vibration control. In well-damped noise/vibration systems, path transfer functions from actuators to sensors can be modeled by finite impulse response (FIR) filters with negligible errors. It is possible to implement noninvasive model independent feedforward control by a recently proposed method called orthogonal adaptation. In lightly d...
متن کاملSelf-tuning Integral Force Feedback
A self-tuning procedure is proposed for an active structural element with collocated sensing and actuation (a so-called ‘Smart Disc’). The procedure aims at optimal active damping by means of Integral Force Feedback control. In case the behavior of the structure to be damped may be described by a single dominant vibration mode, self-tuning is realized in two fairly simple steps: (1) recursive e...
