2013-9-1 · Vibration with hysteretic damping Experiments on the damping that occurs in solid materials and structures that have been subjected to cyclic stressing have shown the damping force to be independent of frequency internal, or material, damping is referred to as hysteretic damping.2016-1-27 · The general solution is then u(t) = C 1cos ω 0 t + C 2sin ω 0 t. Where m k ω 0 = is called the natural frequency of the system. It is the frequency at which the system tends to oscillate in the absence of any damping. A motion of this type is called simple harmonic motion. ItMechanical Vibrations Pennsylvania State University2012-9-18 · The solution of Eq. (2.4) is x = A sin k t + B cos k t (2.5) where the term k/m is the angular natural frequency defined by ω n = k rad/sec (2.6) The sinusoidal oscillation of the mass repeats continuously, and the time interval to complete one cycle is the period: τ= (2.7) The reciprocal of the period is the natural frequency: f n = = = k 1Ralph E.
