This routine outputs the rolling radius, slip angle, and inclination angle of two tires in a dataset. The data is useful in debugging simulations where tire data is being questioned.
Input:
REQ/id, FUNCTION = USER (1129,itire1,itire2)
where:
| | Description |
|---|
itire1 | = | number of first tire of which data is to be outputted |
itire2 | = | number of second tire of which data is to be outputted |
Request File Output
Column Number Output:
1. Rolling radius of first tire (mm)
2. Slip angle of first tire (deg)
3. Inclination angle of first tire (deg)
4. Rolling radius of second tire (mm)
5. Slip angle of second tire (deg)
6. Inclination angle of second tire (deg)
Notes on Input and Output
This request prints out the input parameters used by the tire model in order to calculate the forces at the wheel center. These parameters are rolling radius, slip angle, and inclination angle of the tire to the ground. This request can be used to plot the tire inputs of two different tires in the dataset. This data is useful in debugging simulation runs in which tire data is under scrutiny.
The REQUEST inputs "itire1" and "itire2" are the tire numbers assigned in the Adams dataset. These are the values passed in the GFORCE tire statements.
