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. 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。
A Coupled vibration model of tramcar and track was introduced. 建立了矿车及铁轨耦合振动模型。
