摘要
研究了增量谐波平衡法（ＩＨＢ）在求解三次非线性粘性阻尼双线性滞迟振动系统简谐激励下稳态周期响应中的应用，并通过四阶ＲｕｎｇｅＫｕｔａ数值积分对近似迭代方法的精确性进行了验证，最后根据Ｆｌｏｑｕｅｔ理论讨论了周期解的稳定性．
An incremental harmonic balance method is used to determine the response of the forced vibration of a bilinear hysteretic oscillator with cubic restoring force and viscous damping. The approach is examined by fourth order Runge Kutta numerical integration. The Floquet theory is applied to determine the stability of the periodic solution.
