By means of a systematic design and analysis, this paper establishes a mathematical model for the gearbox energy callback system, and by the use of Matlab/Simulink, it constructs a simulated model for this system, making a simulated analysis of its dynamic characteristics through adopting leaping signals. Factors such as main parameters, elasticity of the model, damping, and turning inertia, which influence the system, are discussed, thus obtaining the system's c...
