Dynamic analysis on virtual prototype of offset centroid exciting efficient vibrating screen
摘要
Abstract
In order to analyze the movement of the efficient vibrating screen in the case of the action line of the exciting force offset screen centroid.A virtual prototype model of TQLZ type vibrating screen was established using Solidworks and ADAMS software.The influence of the location of the action line of the exciting force offset screen centroid to the movement of typical point on the screen body was studied.The results showed that:when the action line of the exciting force passes through above the screen centroid, the synthesis amplitudes and the vibration direction angles of the upper points on the screen increase, while the lower points'are reduced.The amplitudes of the upper screen points are greater than the lower screen points.On the contrary,when the action line of the exciting force passes through below the screen centroid,the movement of the screen is opposite.Regardless of the relative position of the action line of the exciting force and the screen centroid,the trajectory of an arbitrary point on the screen is approximate to a straight line,and no effect on the movement of the screen centroid.The position of the action line of the exciting force offset screen centroid affect the amplitude of y direction of the screen mainly and smaller affect on the amplitude of x direction.The conclusion provides a theoretical basis to design a more excel-lent performance of vibrating screen.关键词
