Abstract:It has important effect for underwater engineering structure and equipment to carry out anti-blast performance experiment research that establishes underwater explosion experimental facility with relative condition fixed. In this paper, a large-sized underwater explosion experimental facility with multiform functions was design and bulited. The equipment includes explsion cistern, lightweight steel sliding and lifting equipment, reserve and pressure experiment, screen bed base, underwater explosion press test systerm and test room. Based on one-dimensional elastic plane wave theory, the primal problem of structure design and anti-blast vibration performance for experimental facility were analyzed. The transmissions of stress wave and damage candition on each medium were researched when longitudinal wave injected the explsion cistern. Bring to bear bubble curtain technology, the feasibility of protective measure for reducing shock wave of underwater explosion was tested and discussed. The rationality of structure design for underwater explosion experimental facility and the availability of protective measure for reducing shock wave of underwater explosion were tested and verified.
