Drive Torque Application for Powertrain Models

In addition to the simple powertrain models, Adams Car supports the modeling of driveshafts in powertrain models. The torque required to drive the vehicle is determined from a torque-speed spline and is applied at the driveshaft. The VTORQUE statement for such a model should be as follows:

VTORQUE/id, I = imrk, JFLOAT = jmrk, RM = rmrk
, FUN=USER (1120, thrid, spdid, splid, sclfac, revlim )

where:

id	=	Vtorque statement id
imrk	=	Marker on driveshaft at which the torque is applied
jmrk	=	Floating marker at which the reaction torque is applied
rmrk	=	Reference marker in whose coordinate system the torque is applied
thrid	=	Variable id to determine throttle position
spdid	=	Variable id to determine engine speed. The engine speed is determined from the average wheel rotational velocities and trasmission ratio
splid	=	Torque-speed spline id
sclfac	=	(Optional) Scale factor for unit conversion of torque (default is N-mm)
revlim	=	(Optional) Revolution limiter for engine speed
