Suspension analysis

[greenamex2]

Hi all

Not really a problem but thought I would ask...

What sort of useful data can you get out of suspension position data?

All I can think of at the moment are spotting a travel issue or a non functioning damper?

Thanks

Suspension position along with I2 Pro math channels allow you to generate lots of channels of useful information.

Starting with suspension position, (and knowing the motion ratio) you can calculate damper position, and by looking at the changes in position over time, you can determine the damper velocity. This is really helpful in understanding the damper speeds achieved so you can valve the dampers appropriately.

By comparing the difference in suspension position from left to right (and incorporating the vehicle track dimension), you can determine the amount of roll at each end of the vehicle.

By averaging the suspension positions at one end of the car, you can determine the ride height changes. You compare the front & rear height difference to determine the change in rake.

Since you know the spring rates, you can determine a reasonable approximation of the downforce front & rear, and the aerodynamic balance that results.

Of course, you can simply use the suspension position directly to tune a droop-limited suspension.

Hopefully those give you some ideas of all the things you can do with suspension position sensors.

Thanks David. Looks like a lot to play with, I'll include them it in my plans.
