ARTICLE ANNOTATION

quote
The article is devoted to the compilation of differential equations of forced oscillations of the grate bar on elastic supports, theoretical solution of strength problems, development of proposals for determining optimal parameters of the grate and reducing metal intensity of the machine. The obtained results can be applied to improve the technology of cleaning machines. Optimal parameters of the elastic supports were experimentally determined: stiffness coefficient C = (1.8÷2.5)×10⁴ N/m, dissipation coefficient b = (80÷100) N·s/m, recommended grate mass m = (1.2÷1.8) Ns²/m. The grate on elastic supports experiences dynamic loads 2–3.5 times less compared to traditional rigid design, which allows reducing metal consumption and increasing cleaning efficiency.
