| 摘 要： | 通过研究双质点模型自由振动特性发现,当质量比与刚度比在某一特定范围内时,二阶振型的贡献度远小于一阶振型的.因此,隔震悬挂结构可由双质点模型等效简化为单质点模型进行计算分析.数值计算对比分析结果表明:由等效单质点模型计算的体系基本自振频率与双质点模型的一阶频率非常接近,最多相差0.3% 左右;两种模型计算的被悬挂结构相对...

| Abstract: | The analysis of free vibration characteristics of double mass model shows that the contribution of the second mode is much less than the first one when both mass and stiffness ratio are in a certain range.For this reason,the computational analysis of isolated suspension structure can be carried out with equivalent single mass model as effective as double mass model.Numerical calculation and comparative analysis show that the fundamental frequency of equivalent single mass model is close to the first order n... |
