Electro-hydraulic proportional speed control on Walking-beam conveyer

Experimental analysis has been done for vibration and noise found in Walking-beam conveyer. Two possible solutions design have been proposed, which integrate with physical components on the speed control system. Because of the determine frequency of the valve, the only way to reducing the opening rate of the valve is using complex signal, which is not what I expect. My research is finding out how to use a simple signal to do complex speed control on Walking-beam conveyer. Through anglicizing the simulation of above design, select the appropriate system for speed control of the Walking-beam conveyer, which provides a theoretical basis and engineering practice for the electro-hydraulic proportional speed control and equipment in the application of non-ferrous metallurgy equipment.
