TY - JOUR AU - Alekseev, A. M. AB - OSCILLATION DAMPING BY PULSED DYNAMIC DAMPERS A. M. Alekseev UDC 534. 282 Dangerous resonance oscillations of various engineering structures and mechanisms can be elimi- nated by using dynamic dampers which, in particular, have nonlinear characteristics of the elastic coupling. One of the versions of nonlinear dynamic dampers is an additional mass which is connected to the main structure by an elastic coupling. Morever, the displacement of this mass with respect to the main structure is restricted by special stops. This type of damper is sometimes referred to as a pulsed dynamic damper (PDD). The dependence of the oscillation amplitudes on the frequency, assuming that the main structure is reduced to a single-mass system which is affected by a harmonic exciting force with an amplitude pro- portional to the square of its frequency, is determined from the solution of the differential equations of mo- tion of the system Mq - Kq -- F (x) = mrrOJ'2 sin o~t; m (;~ + ~) + F (x) = O, (1) where the notation is as in Fig. 1. Restricting ourselves to the examination of the steady-state oscillations with a frequency equal to the frequency of the exciting force, the solution of the TI - Oscillation damping by pulsed dynamic dampers JF - Strength of Materials DO - 10.1007/BF01527575 DA - 1972-02-01 UR - https://www.deepdyve.com/lp/springer-journals/oscillation-damping-by-pulsed-dynamic-dampers-EUkBX0VN3e SP - 179 EP - 181 VL - 4 IS - 2 DP - DeepDyve ER -
