摘要

为研究油阻尼特性从而实现非线性油阻尼振冲隔离器的自主设计及优化，运用理论建模与实验建模相结合的方法，通过大量科学实验和合理的数据处理，根据数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与建模,提出了用于小型电子设备的振冲隔离器的油阻尼特性模型，并进行了部分参数识别。由于体积小，在忽略位移影响的情况下，油阻尼特性模型是按频率分区的，按速度分段的。实验证明，所建模型计算结果比传统线性理论模型计算结果更接近实验数据。

Abstract

The aim is to study oil character for designing and optimizing nonlinear oil damping shock and vibration isolator. Theory modeling and experiment modeling is combined and the nonlinear oil damping shock and vibration isolation is the object to be studied.The oil damper character model is proposed basing experiment data of being processed and graph of data.Some of parameters are identified.Here displacement effecting is ignored because on the electronic equipment displacement of the isolator is small.Oil damping characteristic model has been proposed according to frequency zoning and according to velocity segmenting.The result is excelled that is proved by experiment.
