I am unable to plot the value for Frame yaw rate vs time for forced analysis in two wheeler simulation in the motionview, can anyone help me out?

    Hello Gabriel,

    Please elaborate on "forced analysis".

    For regular events, Yaw rate is available as a default output in models that are built from the two wheeler library. You can find this in the "Instrumentation" system:

    Is this what you are looking for?

    If not, you could also create your own output expression and then plot it while post processing.

    Hello,
    I think What is meant by forced analysis here is, let's say your two-wheeler model is traveling in a straight line and a torque disturbance is given to it, we can see how stable the two-wheeler is by measuring the yaw rate of the two-wheeler.
    I think sinusoidal steering is used in this

    Hello Draucis,

    For the use case that you mentioned, there are two options: Pulse steer and Stability.

    You can explore these two events and use the one that you feel is appropriate for your case.

    To my understanding, sinusoidal event is typically used to evaluate the on-center handling behavior of the vehicle.

    Regards
