TIME ANALYSIS OF A CONSTRUCTIVELY NONLINEAR SYSTEM WITH ONE-WAY CONNECTIONS

An active method of suppressing wind auto-oscillations an overground gas pipeline model is considered, which allows the system to be tuned from resonant frequency by changing its design scheme with help a vibration damping device operating on principle one-way con-nection (OWC). A new mathematical vibrations symmetric form natural proposed. Variants models one and two OWC, located in central span pipeline, are considered. The implementation non-stationary dynam-ic process carried out within framework theory temporal analysis for over-ground multi-span continuous beam point masses sections model. equation motion presented matrix Duhamel integral, taking into account internal friction, follows disproportionate Computer simu-lation problem 39 degrees freedom out. kinematic force pa-rameters dynamic response dissipative obtained, comparative proposed oscillation OWC given, efficiency shown.
