Straight Line Acceleration
A Straight line acceleration event simulates a vehicle accelerating at a constant rate in a straight line.
The event is designed to characterize the chassis behavior during acceleration. The Altair Driver maintains the acceleration rate in the model. Output Requests are included to measure the vehicle behavior, tire response, and other common vehicle system metrics. A plot template is available to plot the results.
Figure 1.
The parameters available in the Straight Line Acceleration event are detailed in the
following table:
| Parameter | Description |
|---|---|
| Velocity | Initial vehicle velocity (meters/second). |
| Desired acceleration | Desired Acceleration rate (G). |
| End time | Absolute end time of the event, in seconds. |
| Print interval | Data is output to the plot files and graphics file at this time interval (seconds). |
