Front Suspension Static Vehicle Characteristics (SVC)

SVC is a set of utility routines used to compute Static Vehicle Characteristics such as wheel rate, anti-dive, anti-pitch for suspensions.
The CONSUB can be invoked to perform a front suspension SVC by typing the following control command:
CONTROL/FUN=USER (1112,jpr_ary,cflag,tflag,vflag,ctime)
where:
 
jpr_ary
=
Id of array containing the necessary jprims, motions, sforce ids to perform the static equilibrium
 
 
 
cflag
=
(Optional) Units Conversion Flag (default = 0)
0 = output units the same data-set units, no conversion performed
1 = output in converted units. The SVCs are calculated in data-set units then converted according to the conversion factors provided in ARRAY/9912 and labeled according to STRING statements 1, 2, 3, 4, and 5.
2 = output SVCs in both converted units and data-set units
 
 
 
tflag
=
(Optional) Tire Forces Flag (default = 0). tflag is ignored for Full-Vehicle Analysis,
0 = Suspension is not supported by tire forces
1 = Suspension is supported by tire forces
 
 
 
vflag
=
(Optional) Verbose Flag (default = 0). If the verbose flag is enabled, the 18x18 front suspension compliance matrix and/or the 12x12 rear suspension compliance matrix are output to the Adams Message File.
0 = Verbose messages off
1 = Verbose messages enabled
 
 
 
cflag
=
(Optional) Current Simulation Time. (defaults = 0) SVC calculations are performed at the beginning of the simulation. If, for some reason the user performs a transient or quasi-static simulation before issuing the CONTROL command, input the current simulation time using this parameter.
The Static Vehicle Characteristics (SVC) DOCUMENT discusses in detail the additional arrays and strings required in a dataset to perform SVC analysis.
