In Tire Test Rig Longitudinal slip test, are you allowed to add more vertical load cases (shown in the picture attached)

Hi Steven,

Yes, You can add more vertical load cases in tire test rig. To do that, you have to update the Test Rig Settings dataset . Once you update the dataset, it will appear in vertical load form.

Thanks for your quick solution.

I have another question: When run the longitudinal or lateral slip tests, the curves have hysteresis (see picture attached). 

Is there a setting to turn the hysteresis off?

Is there a way to combined the looped curve into a single curve. I am thinking, if you average each looped curve, it will combine the upper and lower section into one which is average of upper and lower sections. But how to achieve it with commands?

Thanks,

Hi Steven, 

Tire shows hysteresis when cyclic load is applied as it is a hyper-elastic material. You need to change the parameters in tire property file to remove hysteresis.

You need to go through Hypergraph tutorials to average out the curve otherwise you can export the curves in csv file and average out in Excel sheet.
