| description | Tumbling drums are widely applied in various mechanical engineering branches. The basic deficiency of such technological machines is high intensity of the sound radiation. In modern drums, quiet drives are applied. In practice, the excess of the sanitary noise code is created by the sound radiation of the drum body under the operating environment. The investigation of the dynamic interaction behavior of the environment and drum barrels is resulted. R – ε method of the media turbulence records is used in the present work. According to this approach, Navier-Stokes system of the equations and the continuity equation are used in describing the granular medium motion. The finite-element model geometry meets the form and the sizes of the CF1×18B tumbling drum. The drum axial symmetry has allowed constructing one half of its sectional elevation passing through the geometric centre. Medium energy flows affecting the drum barrels are defined for the calculated ambient velocities and normal velocity components on the boundaries, wall pressure. This data allows calculating theoretically the acoustic characteristics of the tumbling drums. |
