Computes the forces and torques acting on a single tire
Input:
REQ/id, FUNCTION = USER ( 1102,fscale,mscale,tire(1)...tire(n)) )
where:
| | Description |
|---|
fscale | = | scale factor to be multiplied to the translational forces (1.0 = Newton's) |
mscale | = | scale factor to be multiplied to the rotational moments (1.0 = N-mm) |
tire(1)...tire(n) | = | tire number as specified in GFORCE statements |
Request File Output
Column Number Output:
1. Scaled longitudinal (X) tire force
2. Scaled lateral (Y) tire force
3. Scaled vertical (Z) tire force
4. Scaled overturning moment (X)
5. Scaled braking/traction torque (Y)
6. Scaled aligning torque (Z)
Notes on Input and Output
Specifying more than one tire ID will give the cumulative force from each tire.
The forces and torques are calculated at the wheel center with respect to a coordinate system whose Z axis is aligned with Global Z and X and Y are shadow vector of spindle axes on the road.
To obtain forces in pounds and moments in inch-pounds, use the following scale factors:
fscale = 0.22482 lbs/N
mscale = 0.0088512 in-lbs/N-mm
