Investigation of stochastic resonance effects in problems of wind induced vibration
Original language description
We study the response of a dynamic non-linear single degree of freedom system with cubic characteristic to a combination of additive random noise and external deterministic periodic force. We apply the principles of stochastic resonance in the field of wind engineering to investigate vibration of a slender prismatic beam in a cross flow with a turbulence component. The aim of the study is to find such parameter combinations which should be avoided in practice to eliminate response amplitude increase dueto the effect of the stochastic resonance. We assume the non-linear oscillator (beam) with one generalized degree of freedom in the divergence-like regime. It is described by the version of the Duffing equation. We conduct the theoretical investigationwith the use of relevant Fokker-Planck equation together with a verification by numerical simulation of corresponding stochastic differential system. Real characteristics of the beam sectional model investigated in the wind tunnel are emp
