摘要
运用数值计算和计算机图形识别相结合的方法,研究了包含九个参数的Duffing-van der Pol非线性振动系统。通过绘制该系统的时程曲线、相平面图、Poincaré映射图、功率谱图和吸引子图等来判断和研究混沌现象。
By the help of numerical analysis and graphic recognition, Duffing - van der Pol non - linear vibration system with 9 parameters has been researched, the Graphic User Interface contains initial conditions, 9 parameters, power spectrums, trochoid chart of phase portraits, Poineare mapping, analogous dynamic graph of displacements and the analogous vibration graph of mass blocks, the various dynamic characteristics of the non - linear vibration can be attained, which makes it possible to fully implement the visualized computer experiments and study of Duiffing - van der Pol non - linear vibration system.
