【Abstract】

<正>We conducted a set of experiments with reinforced concrete targets that had an average compressive strength of 35MPa and 100-mm-diameter,20-kg projectiles. The ogive-nose projectiles were designed to contain an overload measurement system and launched to striking velocities at 304 and 452m/s.Thus,the overloads during launch and penetration were recorded.The peak rigid-body overload was 40553g.The striking velocities obtained from single integrations of the overload-time data and penetration depths from double intergrations showed great agreement with the test results.Consequently,the overload measurement system we presented was reliable and the recorded overload reflected the truth.
