Dynamic Stress Study of a Similarity Simulation Model for Linear Vibrating Screen
直线振动筛相似模拟动应力研究

Dynamic stress test was carried out for a similar experimental model of 27m2 large-scale linear vibrating screen. The maximum dynamic stress and strain at key points on the screen beam, plate of test model were obtained. According to the similar relationship of working parameters deduced from dimensional analysis and equation analysis, through the comparison between experimental results of the prototype of vibrating screen and similar experimental model, the consistency and reliability of the similar experimental model are proved. Thus the validity of the dynamic test and analysis for the cutdown similar experimental model are verified. Above resilts provide theoretical evidence for improving working life and structural optimization of linear vibrating screen. It also provides reference for further development of similar experimental models.
