Research on variable parameters of SIMULINK based Mould hydraulic vibration system

Based on the mould hydraulic vibration mathematics model in connection with actual operation of the hydraulic vibration equipment,the present paper analyzed the dynamic characteristics of the mould hydraulic vibration system with the MATLAB/Simulink module.Simulation has been made on the displacement of the hydraulic cylinder output under the conditions of different control parameters and different hydraulic component characteristic parameters.Results show that the dynamic characteristics of the system can be improved by reducing the load stiffness and load viscosity,increasing oil source pressure and oil volume modulus of elasticity in an appropriate limit.
