Abstract

The vibrating screen with statically indeterminate mesh beam structure (VSSIMBS) is a novel type of large vibrating screen, which is widely used in coal preparation plants due to its high strength and processing capacity. In this study, the VSSIMBS motion differential equations were obtained via on Lagrange equation, and the dynamic vibration system model was established. The eccentric block force conditions during the operation were analyzed, and the stable vibrating screen operational conditions were obtained. The electromechanical coupling simulation model of VSSIMBS was built in Simulink, allowing frequency control and vibration synchronization experiments. Experimental frequency control results have shown that when the output characteristics of both motors are either the same or similar, synchronous movement can be achieved. Regarding vibration synchronization, experiment results have shown that when two motors are in synchronous motion, and the power supply of one motor is cut off, they still can operate synchronously. Thus, the experimental results obtained in this study provide a theoretical reference for improving the motion stability of large vibrating screens.

基于机电耦合仿真的新型振动筛动态特性分析

超静定网梁结构振动筛（VSSIMBS）是一种新型的大型振动筛，具有较高的强度和加工能力，在选煤厂得到了广泛的应用。本文利用拉格朗日方程建立了VSSIMBS运动微分方程，建立了振动系统的动力学模型。分析了振动筛运行过程中偏心块受力情况，得到了稳定的振动筛运行条件。在Simulink中建立了VSSIMBS的机电耦合仿真模型，进行了频率控制和振动同步实验。实验频率控制结果表明，当两台电机的输出特性相同或相似时，可以实现同步运动。关于振动同步，实验结果表明，当两台电机同步运动，其中一台电机的电源被切断时，它们仍然可以同步运行。因此，本研究的实验结果为提高大型振动筛的运动稳定性提供了理论参考。
