| 内容記述 | This study introduces a design workflow for spaceborne knives that mitigates risks posed by the Dzhanibekov (tennis-racket) effect, which makes objects tumble unpredictably around their intermediate inertial axis in micro-gravity. Three knives were reverse-modelled in CAD, their centres of mass and inertia tensors extracted, and their free-spin trajectories animated in Blender from numerical simulations. The visualisations revealed how mass distribution influences unsafe knives during rotation. Drawing on these insights, the author proposes a micro-gravity steak knife whose centre of mass is shifted forward via handle light-weighting, spine thickening and a spherical tip, while all exposed edges respect ISS “sharp-edge” standards. Iterative simulation confirmed reduced rotational hazard and easier capture if the knife drifts. The study demonstrates that coupling inertia analysis with CG visualisation yields practical design guidelines for everyday tools in orbit and can be extended to other space-product categories. | |||||||
