The harmonic balance method(HBM)was employed to solve the forcedresponse of damped blades considering nonlinear feature of differential equations.
针对该微分方程的非线性特点，采用一阶谐波平衡法，进行了动力响应的计算分析。

N this paper, four factors method for calculating the first-order linear circuit is proposed. Concerned with the forcedresponse in this method, two kinds of new calculating methods are presented.
