Hi There
I am doing a little test program for some tire testing and just need to make sure I am doing something right, I am calculating the radius of gyration of my tire and wheel separately using the formulas from Dunlop http://www.dunlopaircrafttyres.com/tech_support/dunlop-engineering-data.aspx So I have a value of k for the tire and wheel, do I just add those two together to get the combined radius? I do that currently but it leaves me with a value of k that is outside the radius of the tyre, ie for a tire whose diameter is 0.36m I get a k value for the rim of 0.201 and for the tire of 0.239 so combined it comes to 0.44 which feels wrong to me. Can anyone see where I am going wrong?
Chris
