Multi-dimensional waveform analog correction method and control device

The invention discloses a multi-dimensional waveform analog correction method and a control device. The control device comprises a computer, an analog output card, a data acquisition card and an acceleration sensor, wherein the analog signal output end of the computer is connected with the analog signal input end of a controlled vibration table through the analog output card, and the controlled vibration table is connected with the data signal input end of the computer through the data acquisition card after an acceleration signal of the controlled vibration table is sent to the acceleration sensor. The control device is high in control accuracy, has one-to-six-dimensional waveform analog capacity and is suitable for multi-dimensional waveform analog control. In addition, channel numbers can be flexibly adjusted according to different-dimensionality waveform analog demands. By adopting the correction method, test procedures are optimized, and the satisfied test effect can be obtained only through iteration for 2-3 times (one-time half magnitude order, and full magnitude order for 1-2 times). The control device further has the advantages of being simple in system, provided with few modules, easy to install, convenient to maintain and the like and is very suitable for seismic wave analog, road analog and other waveform analog application fields.
