For an ordinary damped vibration system, damping force is in direct proportion to velocity.
This paper focuses on the study of damped vibration. The encoding of 29 characters has far exceeded the requirements of damped vibration in the [PHI]-OTDR technique.
When [[alpha].sub.j] < 0, the complex mode will cause the system to undergo a damped vibration with decreasing amplitude, and therefore this mode is a stable one.
The logarithmic decrement method was applied to determine the modal parameters (Aristizabal et al., 2003), which is the amplitude reduction rate of a free damped vibration, defined as the natural logarithm of the ratio between any two successive amplitudes measured in the same direction (Beards, 1996).
In the system is a damped vibration frequency, in contrast to the first case, where the resonance frequency is the frequency of damped vibration of the system.
The 70 selected papers here cover precision measurement, mechatronics, damped vibration and sound, optical measurement, electrical measurement, measurement in social life, pattern measurement, and signal and image processing.

Previous expression could be easily derived from corresponding differential equation of damped vibration. It is shown in [2] that beam deform according to buckling eigenmode.
This is calculated as the natural logarithm of the ratio of two successive amplitudes under free damped vibrations. As vibration isolation occurs by the conversion of mechanical energy to thermal energy, it is necessary to assess quantitatively the generated heat to avoid overheating of the vibration isolator.
5 the diagrams of free damped vibrations of the system at all generalized coordinates are given.
It covers analytical dynamics of discrete systems, undamped and damped vibrations of n-degree-of freedom systems, continuous systems and their approximation by displacement methods, solution methods for the eigenvalue problem, and direct time-integration methods.
