Visualization of Computing Model of Locomotive Dynamics

A locomotive dynamics simulation systemgenerally consists of model building, model calculation and model display. This paper puts forward a CAD method that is based on three-view drawing. In this method, the initial data chains of a locomotive dynamics simulation model can be visually attached to a graphics interface to build the geometry model of the locomotive dynamics simulation, which is convenient for model building and modifying, and also convenient for the model to be passed to its simulation calculation. Meanwhile, on the basis of the results of the model calculation, a three dimensional animation based model dynamic displaying method is proposed, which can realistically simulate the model simulation results and efficiently check the properties of the locomotive dynamics model. These two research items can further improve the integration of locomotive dynamics simulation systems.
