For the purpose of engineering application, based on theory of multi-body system dynamics, the mathematic theory of virtual prototype technology, physical model’s simplification and dynamic parameters’ specification were introduced in this paper.Taking artillery draught system as research object, depending on some given data, applying the software ADAMS and Pro/E to build dynamic models and the primary components such as vehicle body model, artillery model and suspension model, then compile a lot of tire property files and road property files to build tire models and intensify road models, and mounted them into 3D dynamics model under tractive case.On those intensify road, the guns were draught in different velocity, and the dynamics was computed, dynamic properties of gun and tractive vehicle were got. And these parameters were applied to analyze the artillery tractive system. Moreover fourier transformation was used to convert these data to frequency domain and analyzed.Finally, through the tractive experiment, those dynamic parameters were measured, and these data were used to protract to curves, which were compared with the simulation results, and it proved the simulation was correct.
