Abstract
Present study deals with the finding the damping ratio experimentally for different methods and diffentiate between methods, such as Logarithmic decrement. Circle fit Method, F-D curve, half power method, and Sine sweep method. The assumptions followed is linear system where its dynamic behavior can be described by a second order diffential equation in It is time invariant, It is under damped system. MATLAB coding developed for above methods. Damping ratio is formulated and discussed for different methods.
