| Abstract:This study conducted a simulation study on the precision cutting process of reconstituted tobacco leaf， obtained the mechanical properties and interaction parameters of the materials and provided the necessary data for the finite element simulation. The mechanical model of reconstituted tobacco leaf was established， and the corresponding finite element simulation model was constructed. In the finite element simulation process， the formation process of shear fracture and the change trend of hydrostatic stress with time were analyzed. The effect of shear gap on the section quality of reconstituted tobacco leaf was analyzed by combining finite element simulation and experimental measurement. The results showed that with the increase of shear gap， the collapse angle height of reconstituted tobacco leaf gradually increased， the height of shear zone decreased， and the height of fracture zone increased. However， when the shear gap was 0.15 mm， the height of the shear zone increased slightly and the height of the fracture zone decreased slightly due to the overlap of the upper and lower cutting edges. It was noteworthy that the finite element simulation results were consistent with the measured results， which verified the reliability and accuracy of this study. |
