| Abstract: | A centrifuge shaking table has recently been established in Tsinghua University and applied to analyze seismic soil- structure interaction. Performance requirements and configuration of the data acquisition system for the shaking table were introduced in this paper. The performance test procedures were described in details by using varieties of transducers under static and dynamic conditions. Test results indicated that acquisition system had high sampiing rate, acceptable accuracy and was seldom affected by electronic interference. It was also able to obtain, transmit and treat analog signal in time under 1 g or Ng centrifugal acceleration, providing experimental support for its feasibility. |
