Sinusoidal Steering
A Sinusoidal steering event simulates a vehicle driving at a constant speed while a sin wave input is applied to the steering wheel.
The event is used to simulate the On-center steering test described in SAE paper 840069. Standard vehicle outputs are included in the event. Body state variable output requests (displacement, velocity, acceleration) are included in the body system and tire output is included in the Tire System. A plot template is available to plot the results.
Figure 1.
The parameters available in the Sinusoidal Steering event are detailed in the following
table:
| Parameter | Description |
|---|---|
| Units | Velocity unit selection (Model, m/s, km/h, mph). |
| Velocity | Initial vehicle velocity. |
| Steer Amplitude | Amplitude of the steering input (degrees). |
| Lean Amplitude* | Amplitude of the lean input (degrees). |
| Frequency | The frequency of the steering input (hertz). |
| End time | Absolute end time of the event, in seconds. |
| Print interval | Time interval of data output to the plot file (.plt) and graphics file (.h3d). |
*Applicable only for Two-wheeler events.
