摘要

橡胶支座以及支座与柱串联系统的动力稳定性分析是涉及到这类结构系统安全性的基本力学问题。针对工程普遍关心的橡胶支座与柱串联系统的动力稳定性问题,建立了一种稳定性分析的半解析解法模型,并对不同的情形运用Lagrange方程推导出基于小挠度理论的运动方程,利用数值方法得到橡胶支座与柱串联系统的振动频率,并通过算例进一步探讨了动力稳定性的验算方法。
The dynamic stability of rubber isolators and the system of serially connected isolated structures is a basic problem of mechanics concerning the safety of this type of structures.To counter for the dynamic stability of rubber isolator serially connected with isolated structures which has become a technical problem arousing extensive concerns from engineering circles,a semi-analytical model for analysis of dynamic stability is proposed.With the equation of motion derived using small deflection theory for several different cases,the dynamic stability range of laminated rubber bearing serially connected with column is obtained using numerical method.
