| Abstract: |
| To provide a reference for the body design optimization and operational debugging of multilayer combined rotary screen,the dynamic model of large-yield multilayer combined rotary screen was theoretically analyzed, the motion equation and dynamic parameters of the screen body were derived, then the dynamic modeling simulation was carried out through virtual prototyping technology. The transient motion trajectory during the start-up process of the screen body and the motion trajectory during stable operation were obtained, and the relationship between key parameters affecting the safety (maximum amplitude) and efficiency (rotation speed and rotation radius) of the screen body were analyzed.The results indicated that the motion of the screen body gradually transitioned from elliptical to approximately circular. The radius of the perfect circle corresponded to the rotation radius during the steady-state operation of the screen body. The rotation speed was negatively correlated with the rotation radius during stable operation and positively correlated with the maximum amplitude during the start-up process. |
