CALCULATED DEPENDENCIES AND ESTIMATES OF FREQUENCIES AND VIBRATION MODES OF SHELLS OF RAIL TANK WAGONS

For the English full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT The article gives the procedure for calculating the frequencies of natural oscillations of a shell of a railway tank wagons, taking into account its incomplete filling with liquid cargo. This task is relevant, since it is related to the conditions of safe operation of rolling stock. In this formulation, the solution of the problem is, of course, not done by the finished tracing paper. Including using the hypotheses of the absence of annular deformations of the shear of the shell of the tanks. The reliability of the calculated results is also confirmed by the experimental data obtained in time when testing eight-axis tanks. Keywords: rolling stock, tank car, rail tank wagon, tank oscillations, semimuscular theory of shells, natural frequencies, underfilling of liquid cargo.
