Simulation and analysis of launching process of hydraulic stretching-out and drawing-back launch system

为了研究液动冲压发射系统的工作特点,分别建立了该发射系统的主要组件如蓄压器、发射阀、冲压器的数学模型。在此基础上,进行了整个液动冲压发射系统发射过程的仿真计算,并对仿真结果进行了分析。结果表明:所建立的数学模型正确,基本反映了发射过程中的各主要部件的动态特性。这些模型不仅可用于分析液动冲压发射系统的工作特性,还可为该系统的总体论证与关键部件的设计提供理论依据。

In order to explore the operating characteristics of the HSOADB（hydraulic stretching-out and drawing-back）launch system,mathematical models are established for the accumulator,launching valve and HSOADB instrument which constitute the system.The simulation of the launching process is fulfilled by use of the simulation program based on the mathematical models.The result shows the dynamic characteristics of the main components and proves the mathematical models to be correct.These models can not only be used to analyze the operation principles of the HSOADB launch system,but also provide a theoretical basis for the design of this kind of launch system.
