摘要
利用改进后的规范形理论研究了四维三阶非线性系统最简规范形的计算.介绍了计算四维非线性系统最简规范形的改进方法,得到计算四维非线性系统最简规范形的通用公式.通过对一个实际振动系统的分析,用数值仿真方法验证了该方法在研究高维非线性系统中的有效性.
This paper develops a new computation method for obtaining a significant refinement of the normal forms for high dimensional nonlinear systems. Several ex compute the coefficients of the simplest normal form an pli d cit formulae are derived herein, which can be used to the associated nonlinear transformation. Through the illustrative example, the feasibility and merit of this novel method are also demonstrated and discussed.
