Rear Suspension Anti-lift and Anti-squat

Computes the anti-lift and anti-squat of a rear suspension
Input:
REQ/id, FUNCTION = USER (1113,m9id,mw10id,mb10id,wb,pbrk,cgh)
where:
 
 
Description
m9id
=
MARKER id for point 9
mw10id
=
id of a MARKER at point 10 attached to wheel
mb10id
=
id of a MARKER at point 10 attached to body
wb
=
vehicle wheel base (mm)
pbrk
=
percentage of braking at front axle (between 0 and 100)
cgh
=
height of vehicle center of gravity (mm)
Request File Output
Column Number Output:
7. Percent anti-squat for an independent rear suspension (%)
8. Percent anti-squat for a solid axle rear suspension (%)
9. Percent anti-lift for rear suspension (%)
10. Roll center height for rear suspension (mm)
11. (not used)
12. (not used)
Notes on Input and Output
This request can only be accessed for half or quarter vehicle suspension models. Also, the analysis must be run using "kinematic analysis" since the routine uses velocity vectors to establish the location of the instant centers.
