Oscillations at lean angle

Mattia_pugnaghi

I'm using motionview with vehicle tools, using the motorcycle and events. I have a problem of oscillations when trying to maintain a certain constant lean angles. I've tried a lot changing the PID controllers but cannot get rid of the problem, any suggestions?
(it happens at any lean angle, it is not a consequence of limit of grip on the tires)

Hi @Mattia_pugnaghi,

Is the vehicle you are completing this analysis with one of the example models or is this a heavily modified assembly vehicle?

If your mass/cog/inertia values are incorrect, then it may be effecting the stability of the vehicle and the Driver Model is unable to compensate for it. Alternatively, it could be that the PID values you have chosen are not suitable for this vehicle configuration.

I would recommend the following:

• Confirm the mass, COG, and inertia for all bodies is correct
• Reset the Driver Model parameters to default
• Reset the Global Solver Settings to default for all tabs (Linear, Transient, etc.)
• Rerun the constant radius lateral acceleration event and post an animation of the results here

Hope this helps!
