Wheel offset?

Jesper Slattengren
Jesper Slattengren over 9 years ago
So when I modify the tire/wheel, there is a field for wheel_offset. Which makes perfect sense. The wheel center is a design position on the intersection between the spin axis and the mating surface where the wheel is bolted on. On this design, different wheels can be used with different offsets. That will among other things change the scrub radius.
The problems are
  1. This parameter is not used by anything. Changing it does not move the tire in or out.
  2. Using the suspension testrig, there is nowhere to set this parameter. As this is using a testrig tire that does not expose this parameter. I can change it by manually search for this variable and change it. But it looks like an oversight. And it does not change the scrub radius or anything else in the simulation
 
OK, it is easy to fix for the full vehicle tire template, but it seems wrong to me.
 
Anyone else looked into this? @Martin Kieltsch​ you must have fixed this?

    @Martin Kieltsch​  the way you propose is the safe way as it would work with the suspension testrig wheel, but I hate to do it that way as the offset is a property of the wheel, not the suspension.
    Regarding your second answer: It seems like a big confusion from whoever created this template in the first place (likely not with MSC anymore) as there is a separate field for cm-offset compared to geometric offset. It seems like these two variables have been confused at some time.
