振冲隔离器油阻尼特性的试验建模研究

以非线性油阻尼振冲隔离器为研究对象,物理模型为单自由度、阻尼元件与线性刚度元件并联.运用现代计算分析方法,通过大量科学试验及合理的数据处理,根据处理所得数据及显示的图形结果进行油阻尼特性的非线性分析及建模,提出了在小型电子设备中适用的振冲隔离器的油阻尼特性模型,由于其体积小,在忽略位移影响的情况下,油阻尼特性模型是按频率分区、按速度分段的.文中给出具体实例进行了详细的说明,并初步进行了理论分析和探讨.

The Experimental Study of the Characteristics of Oil Damping

In the paper, the nonlinear shock and vibration isolator by oil damping is the study object. The physical model is a single-degree of freedom system, whose damping element and stiffness element are paralleled. Modern calculation and analytical method is used. The characteristic of oil damping is modeled by using the processed data and graph of damping force. Here the displacement effect is ignored and displacement of the isolator is small on the electronic equipment.A characteristic model of oil damping has been proposed according to frequency zoning and velocity segmenting. The example is presented and the analysis and discussion in the theory are briefly given.
