Three-dimensional physical similarity simulation experimental frame with adjustable angle

Abstract

The invention relates to a three-dimensional physical similarity simulation experimental frame with an adjustable angle. The three-dimensional physical similarity simulation experimental frame comprises an external structural frame and an internal frame, wherein two ends of the external structural frame are provided with an angle determining plate, and each angle determining plate is provided with an angle adjusting track; the bottoms of the front side and the rear side of the internal frame are respectively provided with a guide pulley, the rear end guide pulley is movably hinged with the external structural frame, and the front end guide pulley is matched with the angle adjusting track; and the bottom of the external structural frame is provided with a hydraulic cylinder and a support thereof, and the hydraulic cylinder acts on the internal frame. The three-dimensional physical similarity simulation experimental frame has the advantages that: 1, the operation of the frame is simple, more manpower is saved, and the success rate of experiments is improved; 2, the edge of the frame is provided with an angle value, the angle for the experiment can be directly adjusted, and the experimental process is simplified; 3, the periphery of the frame is protected by using a high-strength transparent materialboard, so that the phenomenon is easy to observe, and results are more realistic; and 4, an open-off cut is reserved, so that the experimental procedure can be simplified, and the experiment is more realistic and simpler.

Problems solved by technology

However, due to the simple structure of the experimental frame in the physical simulation experiment, it is difficult to clearly reproduce many formation conditions, and the model collapses frequently due to various problems during the movement or rotation of the frame (in order to realize the formation conditions with a large dip angle). Caused the failure of the experiment and the difficulty of data collection
