基于透筛物料分布的振动筛姿态控制方法设计与试验
Design and Experiment of Attitude Control Method of Vibrating Screen Based on Material Distribution Through Screen
摘要
Abstract
In view of the lack of reliable automatic control method and poor adaptive ability of multi degree of freedom vi-brating screen,it is difficult to solve the problem of high screening loss rate under the condition of non-uniform feeding of materials.Combined with the developed three degree of freedom hybrid vibrating screen,a attitude control method of vi-brating screen based on the distribution state of materials passing through the screen was proposed.By placing multiple grain counting sensors under the sieve,monitoring the distribution status of the screened grains,and proposing evaluation indicators,a horizontal attitude angle fuzzy controller was designed.The automatic control performance test of the vibrating screen under non-uniform feeding conditions was conducted on a developed three degree of freedom hybrid vibrating screen.The results showed that the designed fuzzy controller can achieve adaptive adjustment of the vibrating screen pos-ture,effectively improve the distribution of materials on the screen surface,and reduce the screening loss rate.关键词
