局部非线性振动系统的稳态频率响应分析

Steady Frequency Response of Vibrating Systems with Local Nonlinearity

本文讨论了带有局部非线性元件的弹性振动系统在简谐激励下稳态周期响应计算问题,给出了应用IHB 法的一般过程,计算了两类带有较普遍代表性的模型,并得到了一些有意义的结果.

An IBH(Incremental Harmanic Balance)process is applied to the analysis of the steady periodic response of elastic vibrating systems with local nonlinear elements under harmonic excitations.The general procedure is given and two typical models with Coulomb's damping are calculated from which some numeral results are obtained.
