Analysis of the electro-hydraulic servo shaking table with flexible payload

The analytical dynamic model of the electrohydraulic servo shaking table dynamic is developed and the interaction between the flexible payload and the shaking table is described with the dynamic characteristics of the flexible payload also. Otherwise, the control strategy of shaking table is interpreted. The systems of shaking table can be controlled better accounting for the dynamic characteristics of the flexible payload (single degree of free SDOF) which is nonlinear, which can reduce iterative steps and improve the precision of earthquake test.
