中文摘要:
      目的 确保发射安全性和为外弹道稳健性设计提供准确的初始出筒姿态参数。方法 用发射动力学建模与仿真技术来研究舰船摇摆对导弹发射出筒姿态的影响。基于同心筒发射系统的拓扑结构,建立其刚柔耦合多体动力学虚拟样机模型。采用Craig-Bampton模态综合方法构建发射筒和导弹的柔性体模型,采用非线性弹簧阻尼模拟导弹与发射筒之间的接触碰撞,基于发动机试车试验数据,采用AKIMA插值方法构建发动机推力模型,根据舰船运动参数,采用正弦函数模拟舰船的横摇、纵摇和垂荡运动。结果 基于建好的模型研究了多种舰船摇摆工况对同心筒发射导弹出筒姿态的影响,获得了相关难于测量的关键设计参数数值。结论 合理的滑块间距和海浪等级可确保同心筒发射系统的发射安全。研究结果对同心筒发射系统设计具有重要的工程价值。
英文摘要:
      Objective To ensure launching safety and provide accurate initial outlet attitude parameters for robust design of exterior trajectory. Methods Launching dynamic modeling and simulation technology was proposed to study influences of ship swaying motion on missile launching outlet attitude. The rigid-flexible coupling multi-body dynamic model was built based on topology structure of concentric canister launcher system. The flexible body models of launcher and missile were built through the Craig-Bampton modal synthesis method. The contact collision between missile and launcher was simulated through nonlinear spring damping. The thrust model was built with AKIMA interpolation method based on engine test data. The roll, pitch and sway motion of ship were simulated through sinusoidal function. Results The research was made on a series of working conditions influence on missile launching outlet attitude. Through this research, some useful values of key design parameters which were difficult to be measured in physical tests were obtained. Conclusion The research results show that the reasonable sliding block distance and sea wave level can effectively ensure launching security of concentric canister launcher system. The research results have important engineering value for the design of concentric canister launching system.
