Project 1
1. Developing a Double-acting actuator model using simscape Multibody and simscape
Cylinder Model
Designing the Mechanical system of the cylinder using simscape multibody library blocks
Cylinder assembly
Piston rod assembly
Designing the Hydraulic system by using the Simscape library physical components
Now adding the two systems with a Translational multibody Interface
NOTE:
Since i am using the Online MATLAB so i can't able to assign/edit the values for the blocks, Please consider my problem
Assumed values that need to change/edit/assign
