To obtain a kind of shaped charge structure which can form high speed penetrator, adjusted the wave-shaper's position of traditional shaped charge structure, simulated forming process of jet by using AUTODYN-2D software. Research shows that setting wave-shaper at a right place close to liner, wave-shaper acts as an auxiliary liner and shaped charge structure can form a similar type of liner which is truncated. Reducing space between bottom of wave-shaper and top of liner can obviously increase head speed of jet and auxiliary body plays a decisive role in improvement of jet velocity. After adjustment, shaped charge structure with wave-shaper of different aspect ratio, jet forming state is well, head speed can up to 10 km/s. The part of pestle is relatively smaller, which can be regarded as a micro pestle.
