求解一类非线性振动问题的谐波平衡法

Harmonic Balance Method for Solving a Class of Non linear Oscillation Problems

用谐波平衡法求解一类在参数激励及强迫激励共同作用下的非线性振动问题．只涉及求解非线性代数方程，不必求解微分方程．文［１］所研究的问题，只是本文的一个特殊情况．

In this paper,using the harmonic balance method,the author seeks to solve the problems for a class of nonlinear oscillations which subject to parameter and forced excitation.We only relate to seek to solve the nonlinear algebraic equations,a need not seeking to solve any differential equation.The problem studied in Ref.is only the special case of this paper.
