Model test device for carrying out underwater explosion research on centrifuge platform

Abstract

The invention discloses a model test device for carrying out underwater explosion research on a centrifuge platform. The model test device comprises a model box, a data acquisition and analysis unit and a synchronous control unit. The model box is internally equipped with a test medium; an explosion device is arranged in the test medium; the bottom of the model box is fixedly provided with a target body; the model box is internally provided with a data receiving unit; the data receiving unit is connected with a data transmission unit; and the data transmission unit is connected with the data acquisition and analysis unit. When the explosion device is detonated, the data receiving unit receives various test data; the test data is transmitted to the data acquisition and analysis unit for processing through the data transmission unit; and the processed data is uploaded to the synchronous control unit. The model test device for carrying out underwater explosion research on a centrifuge platform can be suitable for centrifuge high-speed rotation special mechanical environment, and realizes precise and safe detonation of the explosion device in the centrifugal model test and signal synchronous acquisition and transmission.

Description

Technical field [0001] The invention relates to a model test device for carrying out underwater explosion research on a centrifuge platform, and belongs to the research field of centrifuge explosion model tests. Background technique [0002] Once a large dam is destroyed by an explosion during wartime, and a number of water conservancy projects are collapsed, it will cause huge personal injury and economic loss. Therefore, studying the anti-blast safety of dam engineering has very important theoretical guiding significance for minimizing losses and conducting dam safety assessment. Due to the limited funding and site, it is difficult to obtain the damage mechanism of large dams under the action of explosion load through prototype explosion test research; traditional structural model experiments are also difficult to truly reveal the mechanical behavior and failure process of the explosion prototype. The geotechnical centrifuge increases the gravity of the model through high-spee...
