摘　　要：非对称缸气液联控伺服发射系统在工作过程中无高压空气的泄放,很适用于水中兵器的发射。为研究非对称缸气液联控伺服发射系统的动态特性,在其基本组成及工作原理的基础上,根据气体及液体的物理特性建立系统数学模型,推导出系统的传递函数,并在此基础上仿真分析系统对阶跃、正弦、速度及加速度信号的响应。结果显示系统能很好地跟踪阶跃信号,对正弦及速度信号的响应存在稳态误差,不能很好地跟踪加速度信号。There is no high-pressure-gas emission in the work course of asymmetric cylinder pneumatic hydraulic combination control launching system, so it is suited for the underwater weapon launch. To research the dynamic characteristic of the system, the mathematics model is built up according to its configuration and work principle, and the transfer function is derived. The step signal, sine signal, velocity signal and acceleration signal have been used to test, the simulation shows that the system could be agree with step signal well, and there is steady error to sine signal and velocity signal, and can＇t follow acceleration signal.
