Secondly, the design of the anti-shake mode can also be used to verify the effect of different damping materials or structures for earthquake seismic. The earthquake experience systems allow people to experience magnitude earthquake experience to eliminate the fear of earthquakes, learn self-help earthquake. In order to take into account the experience of safety, boost the experience level acceleration is much smaller than the real earthquake, which prevents the experience of those who fall. Earthquake experience system also can be used the servo screw hydraulic servo valve as the exciter core, the use of electro-hydraulic servo system for all-digital system, vibration rig structure to select non-shock absorption and cushioning two experiential model can be displayed in real timethe seismic waveform and frequency, and rely on the degree of earthquake was felt in selecting the appropriate seismic parameters. Earthquake experience can be a true representation of a vibration direction of seismic waves to create the atmosphere of a real earthquake experience. Finally, due to the combined effect of servo valve, the non-linear effects and stand the test piece, the earthquake experience device is essentially a very complicated non-linear system. For a better understanding of the principle of his work, using a series linearization method, my thesis in the sophisticated equipment makeup of the electro-hydraulic servo shaking table and it works on the basis of the earthquake experience relevant a mathematical model t
