Stan naprężeń i odkształceń w kole wirnikowym z małą liczbą bocznych łopatek promieniowych
W pracy rozwiązano zagadnienie rozkładu przemieszczeń i naprężeń w kole wirnikowym z małą liczbą bocznych łopatek promieniowych, usytuowanych symetrycznie względem tarczy. Opracowaną metodę zilustrowano przykładem liczbowym.
STATE OF STRESS AND STRAIN IN A ROTOR WITH A SMALL NUMBER OF RADIAL SIDE BLADES
The general system of differential displacement equations is given, describing the problem of a rotating circular disc of constant thickness and a rigid hub loaded by centrifugal forces and by radial, axially non-symmetric surface forces p(ρ,Θ) representing the action of side blades. The radial force is assumed in the form of a polynomial and expanded in the circumferential direction into a trigonometric series of period 2π/m (m — number of blades). The unknown coefficients appearing in the polynomial describing the line force p(ρ) are found by equating the radial displacements of the disc and the blade in about 30 points located along the blade. This method is illustrated by a numerical example.
