Roll center height excel

This challenge tests your understanding of roll center construction.
Do these calculations manually (not using a suspension tool like Adams
or MotionSolve to enhance your understanding.

It is advisable to do this exercise in excel sheet so that you can change
hardpoints and study the effects.

Also draw a rough sketch using hardpoints to visualize the suspension.
Remember this is purely a 2d setup(front view) for the left wheel.

Assume the tire radius to be 300mm and the track to be 1600mm.

Assume the setup to consist of links rather than control arms.

X- Not needed ( yz plane relevant here)

Y-Pointing towards the right

Z-pointing towards the top.

Calculate the following geometric parameters.

• Instant center location( coordinates).(5 points)
• Roll center height.(5points)

Answer:
