20.500.12556/RUL-134588 Investigation of cutting performance of a circular saw blade based on ANSYS/LS-DYNA Preiskava zmogljivosti rezanja s krožno žago v paketu ANSYS/LS-DYNA The circular saw blade is widely applied in rock processing; its cutting performance significantly impacts rock processing. Therefore, the numerical simulation model of rock cutting with the flexible circular saw blade has been established to investigate the effects of cutting parameters on the stress and cutting force of circular saw blade, and the damage and stress of rock in the circular saw blade cutting into rock vertically at constant feed speed and rotation speed. The research results indicate that the stress of the saw blade and rock rises with the increase of feed speed and rotation speed of the saw blade. Furthermore, the rock damage and the cutting force of the circular saw blade increase with the increasing feed speed and decrease with increasing rotation speed. The circular saw blade cutting force, vertical force, and horizontal force increase with the rising distance between the double circular saw blade. However, the axial force decreases. The research results of cutting hard rock with the flexible circular saw blade can aid in the optimization of cutting parameters and improve cutting efficiency. circular saw blade rock damage cutting force stress list krožne žage poškodbe kamna rezalna sila napetost podajanje vrtilna hitrost true false true Angleški jezik Slovenski jezik Članek v reviji 2022-01-19 13:15:59 2022-01-19 13:16:04 2022-09-13 03:55:58 0000-00-00 00:00:00 2021 0 0 Str. 649-665 no. 12 Vol. 67 Dec. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.9 0039-2480 10.5545/sv-jme.2021.7322 94094851 RAZ_Wang_Zhiwen_2021.pdf RAZ_Wang_Zhiwen_2021.pdf 1 0E323B078C2372F42CBFE54737B4CFB8 597521249dd9e1c5d291753885da429519019d934b5bde1b5b44c5b563d57d90 77430ed9-7921-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153094 https://www.sv-jme.eu/sl/article/investigate-on-cutting-performance-of-circular-saw-blade-based-on-ansysls-dyna/ 1 63dd44cf-7921-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153093 Fakulteta za strojništvo Strojniški vestnik 0 0 0
