Data of the Truck Model

Every body has a body fixed reference frame attached to its center of mass (CM). Initially the axes of these frames are parallel to the corresponding axis of the inertial frame. The location of the centers of mass is given with respect to the inertial frame, i.e. in absolute coordinates. 

Springs, dampers and constraints are located between attachment points on the adjacent bodies. The coordinates of the attachment points are given relative to the respective body fixed frame.
