Auto-parametric Resonate Analysis of Guyed Mast

给出了桅杆二阶和三阶非线性耦合的模态运动的表达式 ,并用解析法分析了简化的桅杆模型的参数共振 ,最后用数值积分法对一实际的桅杆结构进行了参数共振分析 ,得出了很合理且有意义的结论 。

This paper gives the model motion equation of guyed mast with quadratic and cubic nonlinear coupling. It analyzes the auto-parametric resonance by using the analytic method and using the direct integration method for a real guyed mast structure. On the basis of numerical results, it obtains a satisfying and significant conclusion, and supplies a theoretic foundation for the control of the auto-parametric resonate of guyed mast.
