Abstract.   Dynamic equations of manometric tubular spring are derived and a method for estimation of fundamental vibration frequencies is proposed. Manometric spring is considered as a bent bar executing vibrations in the plane of central axis curvature. Dependences of fundamental vibration frequency of tubular spring on geometrical parameters are obtained in numerical experiments.
Keywords: natural vibrations, manometric tubular spring
