| Abstract: | The electrical system of the 60-gt geotechnical centrifuge is composed of rotate speed control, photograph and video, data acquisition etc. Rotate speed control is implemented via two closed-loop systems with current and rotate speed feedback, through setting up simulant rotate speed and acceleration given by computer. Photograph and video and image surveillance for fixed spot of moving model was accomplished by digital camera, video camera, flash controller etc. Signal measurement, data acquisition, transmission and storage are accomplished by static data acquisition system with 40 channels, and speed adjust parameters, acceleration stability and rotate speed measuring accuracy were analyzed and calculated. System simulation shows this system has stable reliability and higher accuracy. |
