Q-Head Simulator Routine

Computes the sideslip and roll oscillation corrupted sideslip at the front, rear, and C.G. location of a vehicle. This routine assists in correlating Adams model output to actual VDO test data when only Q-head and a yaw rate transducer are used.
Input:
REQ/id, FUNCTION = USER (1123,qhm,lhm,bcgm,lfwcm,lrwcm,lrwcm,rrwcm,grm )
where:
 
 
Description
qhm
=
Q-Head MARKER id on body
lhm
=
L-Head MARKER id on body
bcgm
=
Body C.G. MARKER id on body
lfwcm
=
Left front wheel center MARKER id
rfwcm
=
Right front wheel center MARKER id
lrwcm
=
Left rear wheel center MARKER id
rrwcm
=
Right rear wheel center MARKER id
grm
=
Ground reference MARKER id
Request File Output
Column Number Output:
1. Body sideslip at front axle center (deg)
2. Body sideslip at C.G. location (deg)
3. Body sideslip at rear axle center (deg)
4. Calculated sideslip at front axle with roll (deg) oscillations in data
5. Calculated sideslip at C.G. location with roll (deg) oscillations in data
6. Calculated sideslip at rear axle (deg) with roll oscillations in data
Notes on Input and Output
This routine differs from the other Q-head simulator in that sideslip is calculated using the new Ken Boyd method which employs one Q-head and a yaw rate transducer.
