摘要
基于有限元素法和修正的固定界面子结构模态综合法—Craig-Bampton法,在虚拟样机技术(VPT)仿真平台上建立舰载导弹垂直发射系统(VLS)的柔性多体动力学模型,进行了发射过程的动力学仿真,并和刚体模型的计算结果进行了对比。获取导弹发射阶段的弹道和姿态参量偏差,进行了弹体柔性变形对初始弹道特性和发射安全性影响的分析。
A flexible multi-body dynamic model of ship-based missile vertical launching system （VLS） was built on the platform of virtual prototype technology （VPT）, based on finite element method （FEM） and improved fixed-interface substructure modal synthesis. The dynamic simulation of the flexible model was performed, and the results were compared with that of the rigid model. The trajectory and attitude deviations during launching were gained. The analysis of effects of flexible deformation on initial trajectory characteristics and launch security was completed.
