In addition to the simple powertrain models, Adams/Chassis 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 )


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
