分析了在简谐激励下刚度和阻尼均为非线性的隔振器。考虑了具有对称和非对称恢复力的隔振器。采用谐波平衡法，得到了系统在力激励和基础激励下的稳态、谐响应和传递率。给出了解的线性稳定性分析。一个参数的研究表明，各种类型的阻尼的影响。所研究的系统的次谐波和混沌响应将在随后的论文中讨论。
Vibration isolators having non-linearity in both stiffness and damping terms are analyzed under harmonic excitations. Isolators with symmetric as well as asymmetric restoring forces are considered. The method of harmonic balance is used to obtain the steady state, harmonic response and transmissibility under both force and base excitations. The linear stability analysis of the solutions is presented. A parametric study indicating the effects of various types of damping is reported. The subharmonic and chaotic responses for the systems under investigation will be discussed in a subsequent paper.
