摘　　要：在再生式液体发射药火炮中，贮液室流体系统可能发生由自激振动与强迫振动构成的耦合振荡，在喷射结束期很可能形成共振。文中利用线性化近似方法推导出流体系统压力与流速的传递方程，并分析了贮液室流体系统对于瞬变激励的响应模态，其结论得到了实验结果的验证。这种研究方法对于再生式液体发射药火泡机构设计有重要的指导意义。In the regenerative liquid propellant gun,the coupling oscillation of the fluid sys-tem in the reservoir including free vibration and forced vibration may be formed. At the end ofstorke,there may lead to resonate,Based on the linearizing flow equations,the transfer equationsof pressure and flow velocity are deduced,and the response modes of fluid system imposed thetransient excitation are analysed,its results are agreement with the test data. This analytic methodis important for the mechanism design of RLPG.
