Limit cycle stability of two degree of freedom system under deterministic and random perturbation

Popis výsledku v původním jazyce

Multi-degree of freedom (MDOF) non-linear systems are characterized by a number of response types. Limit Cycles (LC) are of the most important representing typical post-critical response type of many systems. They can be encountered in aeroelasticity, earthquake engineering, high speed traffic mechanics, plasma physics, optics, etc. Stable and unstable LCs should be distinguished. The aspect of stability and non-stability impresses on LC the character of an attractor or a repulser. Normal form of governing stochastic differential system with Gaussian white noise perturbations is considered. LC stability investigation is conducted on the basis of the relevant Fokker-Planck (FP) equation. The stochastic differential system with multi-component additive and multiplicative perturbation is then constructed and transformed into FP equation with respect to special toroidal coordinate system around the LC. Perturbation of PDF stability is then analyzed in the meaning of the mean value and vari
