My method was to project the weight on the line between the middle of the front tires and the middle of the rear tires, use this to find the front/back weight distribution, then do the same projection for the middle point between the left tires and right tires. You can move the tires or blue weights by clicking and dragging. Is there a general solution for such a system?ĮDIT: I have mocked up a testing app, which is available here: In googling for this I've found all sorts of confusing things, and I have a feeling I'm overcomplicating it as a result. Then on top of that, what about adding other components, like a fuel tank offset to one side? If you put it directly over the front axle between the two tires, there'd (presumably) be 1000N on each front tire and nothing on the rear tires.īut what if it were overhanging past the front tires? Would there be less than 1000N on each front tire, and negative load on the rear tires due to the front axle acting as a lever? I've been creating a 2D (above view) vehicle simulation as a hobby project, and (as is often the case) a problem which I assumed would be simple has turned into the sticking point of the project.Įssentially, I want to be able to calculate the total load on each tire given arbitrary vehicle configurations.Īssuming we just had an 200kg engine, and it was placed exactly in the centerpoint between 4 tires, suspended there by magical zero-mass connections, there would be 500N evenly distributed across each tire.
