| 摘 要： | 现有关于非线性阻尼模型建立的方法,仅仅指出了隔振器的动态特性与频率的关系,没有反映出与初始静位移的关系。在其基础上进行改进,指出了与初始静位移的函数关系。此模型体现了隔振器的动态特性与总体结构形状以及变形方式的关系,能更好地反映隔振器的特性。

| Abstract: | In a previous paper, the author presented a method of constructing a model of a vibration isolation cell with nonlinear damping. But the model only indicated the relationship of the dynamic property with the frequency, not including the relationship with the initial static displacement. Based on the above work, the author made some improvement, which indicated the relationship with the initial static displacement. The model presen- ted in this paper can embody the connection of the dynamic characteristic of the vibration isolation cell with the total structure shape and the way of distortion, which can express the characteristic of the vibration isolation elements better. |
