Project 1

First, let's build the mechanical system, followed by the hydraulic system.

STEPS INVOLVED IN BUILDING MECHANICAL SYSTEM USING MULTIBODY LIBRARY

• Open matlab
• Here we have to build a piston and cylinder
• Import blocks required to build cylider and piston such as cylindrical solid, revolved solid,mechanism configuration solver, world frame from multibody library
• Input the parameter values like density, radius,colour,opacity and assemble them by adding frame (left and right)

Now let's connect these piston & cylinder

STEPS INVOLVED IN BUILDING HYDRAULIC SYSTEM USING SIMSCAPE COMPONENTS

• Import Blocks such as Translational mechanical convertor , PS constant , substract, Mechanical translational reference from the simscape library
• Connect these blocks as illustrated in the diagram
• Input the values of PS constant, Bottom chamber, Head chamber related parameters
• Finally connect the both mechanical & Hydraulic system by a translational multibody interface

HYDRAULIC CIRCUIT

VALVE CONTROL SUBSYSTEM

VALVE SUBSYSTEM

Here we can see 4 orifices are connected which is nothing but the 4 ports of a 4/3 DC valve

INPUT SIGNAL

THE FINAL MODEL OF A DOUBLE ACTING CYLINDER

GRAPHICAL RESPONSE

CONCLUSION

The double-acting actuator model that we created and successfully emulated. The piston moves forward and backward in response to the input signal. It can be seen from the graph that the output fluctuates according to the output.
