The dynamic analysis of a rail vehicle can take many forms. Predictions of stability curving performance, or ride quality may be the required output from a dynamic model of the vehicle. Whichever result is required, the equations of motion of a complex set of interconnected mechanical elements must be formulated and solved. This paper describes a computer-based method for automatically forming and solving the equations of motion of any rail vehicle. The general vehicle is assumed to consist of an arbitrary set of interconnected rigid bodies. The interaction of the vehicle with its environment occurs only at the points of contact of the wheels with the rails. The analyst is free to choose the number of rigid bodies, the degrees-of-freedom, and the locations of interconnecting elements. With this information available, the computer is able to form the equations of motion for the multi-body system, apply the wheel/rail forces and solve the system using a technique suitable for the required result. The techniques described in this paper offer significant savings in human effort while giving the analyst freedom to use models which are as simple or as detailed as necessary for the problem at hand.
