Abstract: Disclosed herein is a land based horizontal shock wave tester that simulates double shock waves generated in an underwater explosion. The horizontal shock wave tester includes a first shock wave generating unit, a second shock wave generating unit and a shock wave control unit. The first shock wave generating unit is installed at a predetermined position on a stationary mass on which a specimen is mounted. The second shock wave generating unit is provided to generate a secondary shock wave derived from a primary shock wave input from the first shock wave generating unit by collision of an impacting mass with the stationary mass. The shock wave control unit controls the second shock wave generating unit by using MR damper units so that a period and a magnitude of the stationary shock wave that vary depending on a period and a magnitude of the primary shock wave can be adjusted.
