modifying aevhybrid's in wheel motors wheights and gears

Yannic Wulfdeit

When I modify my in-wheel-motors motor diameters and weight, or gears to fit my actual vehicle my model stops passing static equilibrium

    Okay so I reset all my changes to my wem substystem and there seems to be a different issue with my model. When simulating constant radius cornering the simulation stops after a fraction of the time and looks as follows

    Open Loop simulations work though

    Adams can not solve the equations of motion because the mechanism has

    "locked up". At least one constraint can no longer be satisfied.

    Can you tell me the constant radius cornering setting you ran so I can replicate?
