A software is developed in a visualized computer language for analysis of the trajectory of movement of the nonlinear forced vibration equation. With the software, the trajectories of equations of such a type in phase space, the Poincarè image, the time amplitude curve, and the amplitude frequency curve can be shown dynamically. Based on computer simulation, the dynamic property of chaos can be generally analyzed.
