Mechanism excited by hydraulic fluctuation and its application on simulation vibration screen
Abstract：Studied on hydraulic fluctuation principle,and set up hydraulic exciting system consisted of wave exciter and hydraulic cylinder so that the exciting pinciple was applied on simulation vibration screen to solve the present problems in inertia shock excitation.The system exciting principle is that hydraulic shock waves are periodically produced in pipeline by wave exciter forcing flat so as to drive piston and piston rod as well as loads fixedon it periodic motion,that is exporting vibration.The hydraulic exciting pinciple was applied on simulation vibration screen and test was conducted to study its controlled law in diferent working conditions and various parameters.The test results prove that the vibration screen＇s frequency is independently controlled by excitation frequency of wave exciter.And when its amplitude is defined,pressure is increasing with frequency improving.When its pressure is defined,its amplitude is decreasing with frequency improving.
