摘要
利用虚拟样机技术(VPT)建立了飞行器零长发射过程的动力学仿真模型。详细论述了飞行器发射系统的组成、模型简化和动力学仿真的研究方法。对不同工况下的发射过程进行动力学分析,获取了飞行器发射阶段的姿态参数和发射车的稳定性,验证了飞行器零长发射的可行性和安全性。
Dynamic simulation model in zero-length launching of the vehicle is achieved by the virtual prototype technology （VPT）. Composition, model simplification and dynamic simulation of zero-length launching are discussed. Dynamic analyses in launching under different operating states are done. Attitude parameters during launching of the vehicle and the stability of the launcher are obtained. Feasibility and safety in zero-length launching of the the vehicle are verified.
