Torsional Vibration and stability Analysis by Bond Graph Modelling: A practical approach, part two.

The traditional modelling approach in engineering is mathematical, but thanks to the advances in computer technology it is now possible for the practical engineer to model physical systems in a more “user friendly” way. This paper will demonstrate the power and simplicity of Bond Graphs in modelling technique. Bond Graph modelling was original developed in the late 1950s by the late Professor Henry M. Paynter of MIT. Professor Paynter acted well before his time as the main advantage of his creation, other than the modeling insight that it provides and the ability of effectively dealing with mechatronics, came into fruition only with the recent advent of modern computer technology and the tools derived as a result of it, including symbolic manipulation, MATLAB and SIMULINK and the simulation package 20-sim, which allows direct input of the Bond Graph
