Abstract

On the basis of the review of publications in domestic and foreign press the analysis of a current status of a problem of the theoretical description of the aircraft wheel shimmy phenomenon was spent. Various models such as the classical mathematical models, modern approaches to the description of oscillatory instability of rolling bodies on a hard surface by dry friction first of all are considered. On the basis of results of the analysis offers on the further perfection of the shimmy theory with reference to high-frequency vibrations of aircraft uncontrollable landing gear are formulated.

Keywords:

fluctuations; instability; rolling; dry friction; the chassis of the plane; shimmy шимми
