以地震模拟振动台为例，阐述了液压系统中流体与弹性体结构的相互作用现象，说明了在防震减灾重大试验设备研制中考虑流体与弹性体相互作用问题的必要性．
Taking the seismic shaker as an example, the interaction between fluid and elastomer structure in hydraulic system is expounded, and the necessity of considering the interaction between fluid and elastomer in the development of major test equipment for earthquake and disaster reduction is demonstrated.
