Test and Parameters Design of a Novel Reinforced Cymene-Si-Oil Isolator for Reinforcement Scheme of Flimsy Equipment System in Moving Conveyances

The aim of this paper is to provide a systematic investigation of a reinforced isolator for the protection of flimsy electronic equipments system in harsh vibration environment. A Cymene-Si-oil damping isolator is designed and manufactured through coupling the oil and spring by sophisticated methods. The physical mechanism of the actual isolator is investigated.The results of a prototype in dynamic test show complex nonlinear dynamic characteristics. Based on the test, a nonlinear dynamic model for the isolator is presented by analyzing the internal fluid dynamic phenomenon with respect to the isolator. Comparisons with experimental data confirm the validity of the model. In the meantime, an optimal model for parameters matching design is built based on an approximate solution. Finally, the performances of the applying product are described.
