Simulation of Hydraulic Circuits by using Matlab-Simulink Software

Abstract

Hydraulic actuators can be used in large number of applications like machinery, automobiles, robot mechanical design etc. in present work we choosen closed loop Electro-hydraulic actuator with proportional valve coupled with a feedback system. The time response of the hydraulic actuator is notable especially when it is used for lifting the load. In this view estimating the time response of the hydraulic actuator prior to its usage is going to be very useful to analyze the Effectiveness of the system. Which will also useful to get an optimum design parameters for hydraulic actuator. In the Present work a position control electro-hydraulic linear actuator was choosen which can be used for Monitoring the movements of loads. Numerical Calculations of the hydraulic actuator and its components is done by using the mathematical equations. Matlab/Simulink Software is used to obtain the time response of the linear actuator
