英文摘要：

To provide the reliable mechanical parameters of the fuses during penetration,it is necessary to study the deceleration of the projectiles.The penetration test was carried out for a reduced-scale advanced earth penetration warhead （EPW） into concrete.The deceleration-time curve of the projectile was obtained by a hard recovery technique.The testing system for deceleration is highly modularized,including a testing module,a circuit module,a memory module,a power-supply module and a periphery computer module for data processing.In the testing module,the piezoresistive accelerometer is fabricated by the MEMS technique and it works in a Wheatstone bridge.The projectile mass is about 1.8 kg,including the deceleration testing equipment loaded in it.The maximum diameter of the projectiles is 48 mm,and the striking velocity is 1142 m/s.The deceleration magnitude obtained by the experiment is approximately 20 × 104 g.
