| description | ObjectiveAiming at the problem of significant vibration in the roller movable teeth due to long-term impact loads, a novel lattice roller movable teeth was proposed based on the hollow roller structure.MethodsFirstly, the impact resistance of four lattice structures was analyzed through equivalent stiffness prediction and impact tests, determining the optimal lattice structure and the structural parameters of the lattice roller movable teeth. Subsequently, simulation analysis was conducted to investigate the equivalent stress and vibration characteristics of solid roller movable teeth, hollow roller movable teeth, and lattice roller movable teeth. Finally, a vibration characteristic testing platform of roller movable teeth was established, and the vibration accelerations of different types of movable teeth were comparatively analyzed.ResultsThe results indicate that the proposed lattice roller exhibits a 28.72% reduction in equivalent stress compared to the solid roller and a 3.96% reduction compared to the hollow roller. Additionally, the peak vibration acceleration of the lattice roller movable teeth is significantly lower than that of the solid and hollow roller movable teeth, demonstrating excellent vibration damping performance. The test results align with the simulation trends, verifying the reliability of the simulation model and the accuracy of the test results. The findings of this study can provide a reference for the structural design of vibration reducing movable teeth. |
