Where can I find definitions for the requests that are output when running a full vehicle event in Adams Car?

peter.d'urso
I have looked everywhere in the ADAMS car help and I can only find the suspension output definitions. Where can I find the exact definitions for the requests automatically generated after running a full vehicle model such as:
 
vehicle_mass_properties
vehicle_statistics
chassis_accelerations
chassis_displacements
chassis_velocities
etc...

    You will find many in the testrig within your assembly. Otherwise look into the subsystems where the measurement is done.
  • 0
    Partly you can find it in the help.
     
    Outputs
     
    Otherwise I always recommend checking the adm-file.
    For example the chassis_accelerations look like this:
    REQUEST/277
    , COMMENT = Chassis Accelerations
    , CNAMES = "", "longitudinal", "lateral", "vertical"
    , CLABELS = "", "Acceleration (g)", "Acceleration (g)", "Acceleration (g)"
    , RESULTS_NAME = chassis_accelerations
    , FUNCTION = USER(907, 2, 833, 824, 833, 1, 1)\
    , ROUTINE = abgVDM::req907
     
    Marker/833 is the chassis_cm, MARKER/824 is ground.origo, which means the request obviously holds the accel of ground origo relative to chassis.cm.

    BTW: Help also says
     
    Request 907
    Request 907 (req907) outputs displacement, velocity, accelerations, and body side-slip angle depending on the value of par(2) in the parameter list. Req907 is compatible with both dynamic and steady-state type analyses.
    The definition of the parameters array and the resulting output is:
    par(1) = Branch Flag 907
    par(2) = Request Type:
            0 = Displacement(Angles in radians)
            1 = Velocities    
                 (Translational vel. in KPH)
                  (Angular velocity in radians/s)
            2 = Accelerations
                  (Translational acc. G's)
                  (Rotational acc. in radians/s/2)
            3 = Body Side Slip Angle in Radians
    par(3) = id I marker
    par(4) = id J marker
    par(5) = id RM marker
    Any results with a magnitude less than 1e-7 are set to zero.
