摘　　要：压力振荡抑制技术是再生式液体发射药火炮(RLPG)技术的难点之一。报道通过改变再生喷射活塞系统机械振动的固有频率,可破坏RLPG压力振荡的激励机制。试验表明:利用此方法可有效抑制压力振荡的幅值。研究结果对再生式液体发射药火炮内弹道设计有指导意义。The suppression technology of pressure oscillation is one of diffi-culty of regenerative liquid propellant guns. It is reported that the inspiringmechanism of pressure oscillation of RLPG can be broken by change of inher-ent frequency of mechanical vibration of regenerative injection piston system.The experiments show that amplitude of pressure oscillation can be suppressedby using this way. The research results have instructive significance to interiorballistic design of RLPG.
