| 在非火工分离技术的发展需求下，基于气驱推冲原理的分离机构在国内外多型运载火箭中得到了应用。因其长细比较大，具有显著的弹性效应，开展了导向分离过程的弹性仿真，建立了考虑弹性效应的计算模型，与试验结果吻合较好。通过对载荷、摩擦、约束等因素的分析，揭示了关键参数对分离过程的影响规律，提出了有效实现分离目标的控制要素和设计思路，为推冲分离方案的工程详细设计提供参考。 |

| Abstract: |
| Under the development needs of non-pyrotechnic separation technology, the separation mechanism based on the principle of gas drive thrust has been applied in multi-type launch vehicles at home and abroad. Due to its large slenderness ratio and significant elastic effect, the elastic simulation of the guided separation process was carried out, and a calculation model considering the elastic effect was established, which was in good agreement with the experimental results. Through the analysis of load, friction, constraint and other factors, the influence of key parameters on the separation process is revealed, and the control elements and design ideas to effectively achieve the separation goal are proposed, which provides a reference for the detailed engineering design of the push-impulse separation scheme. |
