Abstract
logical process and reducing energy consumption. Methods: an analytical Euler–Bernoulli cantilever-beam solution is obtained for the
sensing wall of the density-control device under a uniformly distributed centrifugal load ????; the load is derived from the rotational speed of
the working members, the density and thickness of the contact layer of the seed roll, and the radius of the working chamber, and is revised
relative to the earlier calculation. For steel and copper walls of length ???? = 260 mm and width ???? ≈ 180 mm, the required thickness is found
from a strength criterion. Results: the load range is ???? ≈ 0.66–3.63 kN/m; for a safety factor ???????? ≥ 1.5 the steel wall must be at least 5 mm
thick and the hard-drawn copper wall at least 4.7 mm thick; annealed copper is unsuitable. A deflection–density calibration relationship
is obtained and its sensitivity is estimated. Conclusions: correcting the load and the geometry substantially changes the wall-thickness
recommendations compared with the preliminary stage; the proposed procedure provides a justified basis for designing the sensing element of the seed-roll density-control device of a linter machine.
