Project 1
Aim:
To Develop a Double -acting actuator model in simulink using simscape block and mechanical system of the cylinder need to built using simscape multibody library components then the hydraulic system need to be modeled using simscape hydraulic library.
Double Acting Hydraulic Cylinder:
A Double - Acting actuator has two chamber. Pressure is applied alternately to each chamber to extend or retract the position. This design allows it to move back and forth without the need for spring, providing more consistent and reliable motion in both direction.
Double-Acting actuator are often used where precise control of movement and force is necessary. they are found in various system, including robotics arms, industrial machinery, heavy equipment lifting where accurate position is essential.
Setup:
- open simulink and create new model.
- Go to simscape> Foundation Library and add the necessary Blocks for the model.
Hydraulic System Modeling:
Hydraulic Cylinder (Double- Acting): From Simscape> Fluid > Hysraulic Cylinder. Thia block reprecent a hydraulic actuator by fluid power to extend or retract.
Stroke length has 45 Cm (ie) piston travelling distance inside the chamber.
chamber A(Bottom)
Chamber B(Head)
Directional Valve: A 4-way, 3- Position directional Control Valve to regulate fluid to each other chamber of the cylinder.
Place this Valve from simscape > Fluid >Valves & Orifices and configure it to control fluid flow.
Direction Valves :
Orifices Measurements:
Hydraulic Fluid Source: Use a Constant Pressure source From simscape > Fluid > source to supplyn the nescessary fluid pressure.
Reservior: Add a reservoir Block to maintain system Pressure.
Piping And Accumulator: Connect the Cylinder, Valve and Source using Hydraulic Pies for fluid flow, optionally add an Accumulator to manage Pressure Spikes.
