Development on shocking table for blast explosions

In order to simulate the ground shock and vibration under nuclear explosion and conventional weapon blast, according to the principles of energy conservation and elastic colliding, a hanging test table which is used to simulate blast shock and vibration is manufactured. The table can provide shock and vibration in horizontal and vertical direction. By adjusted the parameters, such as the height and weight of the hammer and cushion thickness, the table can achieve the following parameters: the horizontal peak acceleration is 5-1 500 m/s2, the action time is 50-4 ms; the vertical peak acceleration is 5-1 000 m/s2, the action time is 60-4 ms. The experiment result indicates that the table meets the design requests, which provides a safety, convenient, economical, reliable trial means.
