The multifunction tectophysics simulating experiment apparatus is an integrated electromechanical system used for geologic modeling experiment. By comparing the advantages and disadvantages of the vicarious apparatus in home and abroad,the key technologies of tectophysics simulation experiment apparatus were studied. On the basis of analyzing geological formation and evolution mechanism,the stressing and distorting rules of geologic body from the aspect of dynamics and kinesiology were summarized,and the similar model as well as the overall formation structure of the equipment and design of the functional unit of every subsystem were accomplished according to the similarity principles. In addition,the conceptual design and structural design were completed using modular design method. Achieved for the test equipment function and motion control requirements,the distributed three tier solution structure of the motion control system was developed based on programmable logic controller. The results show that the experiment apparatus can complete serials standard tectophysics simulating experiments and the method provides a new technical means for the tectophysics simulation experiment. At the same time,the proposed modular design method and mathematical model of similarity for the tectophysics has laid the theoretical foundation for the development of such experimental devices.
