Hypergravity centrifugal shaking table is widely used in the field of civil engineering. It has the spatiotemporal compression effect that the normal gravity shaking table does not have. The hypergravity centrifugal shaking table is recognized internationally as the most effective method to study the disaster effects of rock and soil earthquakes. The research of the high precision waveform control strategy of the hypergravity centrifugal shaking table is the premise of the engineering application of the hypergravity centrifugal shaking table. In this article, the dynamic characteristics of the normal gravity shaking table and the hypergravity centrifugal shaking table are analyzed and compared, the particularity of the hypergravity centrifugal shaking table is pointed out, and the limitation of the control strategy of the normal gravity correlation is pointed out. On this basis, the compound control strategy of acceleration waveform of unidirectional airborne shaking table with high gravity is designed and verified by experiment.
