Abstract

The grinding table is important for dust control, but its ergonomics design is often overlooked, so this paper designs the upper flange width of grinding worktable combined with dust control effect and ergonomics design. The dust concentration distribution was simulated by using Fluent for different upper flange widths of the grinding worktable, and the L4/L5 force was analyzed by using Jack software for different distances from the outer edge of the worktable to the center of the sharpener. The maximum upper flange width was analyzed by geometry based on human size and CAD drawing analysis. The result is that the wider the upper flange, and the better the dust control effect; the L4/L5 force meets the NIOSH standard requirements regardless of the operating distance; the maximum width of the upper flange is 232.2 mm; if it is greater than 232 mm, it will affect worker operations.
