I just went with the notation of y being vertical (in the direction of bump travel) like Earl used to derive the transfer function. Then I guess X can be longitudinal and Z is lateral. The origin should probably be in the center of the car so for example the coordinates for the front passenger mass would be (I am guessing at the numbers here):
(50",y,30")
I know the X and Z coordinates would actually be a function of Y but for small angles I think this is negligible?
