Abstract

The invention relates to a general waveform reproduction control method and device. The general waveform reproduction control method includes setting test parameters, performing target wave processing, estimating original transfer functions and adjusting order. The control device comprises a computer and a signal interface case. The computer is connected with the signal interface case through Ethernet electric signals and provided with a general seismic modeling control system. The signal interface case is used for connecting controller inner signals and inputting and outputting external hardware signals. The signal interface case integrates an acceleration signal conditioning board, a displacement signal conditioning board, a busbar clamping slot, a single board computer and a power supply module. The general seismic modeling control system comprises a test parameter setting unit, a target wave processing unit, a seismic waveform simulation unit and a signal analyzing unit. By the use of the control method, estimation accuracy of the system transfer functions within full spectrum band is high, and test steps are simplified. The control device is simple and reasonable in structural design and high in control accuracy and has fewer modules and complete signal analyzing and processing functions.
