Abstract: The objective of this paper is to provide a systematic investigation to a cymene-Si-oil shock absorber for protection of precision equipment systems in vibration. The physical mechanism of the shock absorber is systematically investigated. The experimental results of the prototype show complex non-linear dynamic characteristics. A dynamic model for the shock absorber is presented by analysing the internal fluid dynamics phenomenon with respect to the shock absorber. Comparison between the simulation and experimental data confirms the validity of the model. Using the model it is possible to evaluate the importance of different factors for designing of the shock absorber.
