Dynamic Simulation

Environment → Dynamic Simulation

 Simulation settings →
unselect "automatic", then "Yes" keep the rest of the stand joints.

Mechanism Status → [>>]

There are 4 kinematic chains, one for each piston assembly:


Change each of the chains to:

• Revolution → Cylindrical
• Revolution
• Cylindrical → Spherical
• Cylindrical → Prismatic

degrees of redundancy → 0
degree of freedom - 1



Now, right click → properties
enable imposed motion

6000 deg/sec


Prismatic joints → properties→ friction coef = 0.2


Time to run the simulation player!

Open up the Output grapher, and have a look around!

If you have trouble getting everything set up correctly, go through this tutorial with pre-made parts, until you get a feel for how to constrain everything in the first place, and then how to set the Dynamic Simulation Joints.

Note:  You will need to make your own parts!  Do not just copy off of the internet, youwill only get credit if your parts are unique and do not match anything off the internet!
