The invention discloses an adapter for a centrifugal machine underwater explosion test. The adapter includes horizontal fixing poles installed on an inner wall of a model box. Vertical fixing poles are installed between the horizontal fixing poles. A sliding block capable of sliding is installed between the vertical fixing poles. A miniature detonator is installed on the sliding block. The miniature detonator is connected to a spherical charge through a detonating fuse. The detonating fuse passes through a through hole. A first scale is installed on the horizontal fixing poles. A second scale is installed on the vertical fixing poles. The midpoint of the first scale is aligned with the midpoint of the first fixing poles. The midpoint of the vertical fixing poles is aligned with the midpoint of the second scale. The four fixing poles can support the spherical charge, and an adjustable bolt is screwed to adjust the horizontal fixing poles in one plane. The adjustment is convenient. The sliding block is accurately positioned in the model box by sliding an installation base and the sliding block, so that the spherical charge satisfies a detonation demand of the test.
Description
technical field [0001] The invention relates to an adapter for underwater explosion tests of centrifuges, belonging to the application field of centrifugal model tests. Background technique [0002] Once large-scale dams are damaged by explosions in wartime, and then lead to the continuous collapse of multiple water conservancy projects, it will cause huge personal injuries and economic losses. Therefore, the research on anti-blast safety of dam engineering has very important theoretical guiding significance for minimizing losses and evaluating dam safety. Due to limited funds and sites, it is difficult to obtain the damage mechanism of large-scale dams under the action of blast loads through prototype blast tests; it is also difficult to truly reveal the mechanical behavior and failure process of blast prototypes through traditional structural model experiments. The geotechnical centrifuge increases the gravity of the model through high-speed rotation, so that the model me...
