Учёт влияния условий монтажа на напряжённо-деформированное состояние упругих колец в демпферной опоре

Abstract

The article considers the influence of different tolerance values on squeeze film damper elastic rings stiffness. This type of damper is widely used in gas turbine engines supports. Nevertheless, modern analytical solutions have a number of limitations. Missing of slipping and friction effects, different tolerance variations, interaction of two inserted into each other elastic rings. The work shows parametric finite element models of elastic ring, set of two interconnected elastic rings and simplified segment. Attained results show different disalignment for different models comparing with different analytical approaches. Shown the effect of tolerance on flexibility value of elastic rings.
