| Abstract: |
| For the vibration screen system of asphalt mixing plant,a dynamic model based on the Newton method is established.In this model,the direction inconsistency between mechanical vibration and springs support are considered as well as the influence of support bearings and sieve-plate stiffness on the vibration screen system.The variation of vibration displacement of the vibration screen centroid under the different exciter frequencies and the installation angles was investigated.The amplitude distribution of different locations of vibration screen was obtained,and the effect of different vibration direction angle on amplitude and stress was studied by using finite element method (FEM) for steady-state.The results show that the amplitude of vibration screen increases with the increasing frequency of exciter and the decreasing tilt angle of vibration screen.The main amplitude and stress increase with the vibration direction angle β when β varies from 0° to 90°.The amplitude near the feed inlet is greater than that near the feed outlet along the length direction of vibration screen. |
