What Is Meant By Logarithmic Decrement? |
|
Answer» LOGARITHMIC decrement method is used to measure damping in time domain. In this method, the free VIBRATION displacement amplitude HISTORY of a system to an impulse is measured and RECORDED. Logarithmic decrement is the natural logarithmic value of the RATIO of two adjacent peak values of displacement in free decay vibration.
