针对舰载导弹发射问题,进行导弹出筒姿态影响因素研究。基于能量谱原理对舰艇随机摇荡运动进行了数值模拟;利用多体动力学原理建立发射系统模型,分析了舰艇的横摇、纵摇、垂荡、航速和导轨间隙对导弹出筒姿态的影响;建立了参数化模型对间隙进行了优化。分析结果表明,横摇、纵摇及间隙对导弹出筒姿态存在一定影响,垂荡和航速几乎不产生影响。得出系统总体设计方案基本可行,研究为发射系统初步设计评估和再设计提供参考。

As for the issue of shipboard missile launch, the research on the influence factor of the missile muzzle attitude was conducted. The numerical simulation was done for random motion of ship based on the energy spectrum of principle; The multi-body dynamics model of the launch system was built and the influence of rolling, pitching, heaving, navigational speed and clearance on missile muzzle attitude was analyzed; The parametric model was built and the clearance was optimized. The analysis results show that rolling, pitching and gap would influence the muzzle attitude of the missile, but the heaving and the gaps do not. The conclusion is that the design project for the system is feasible, which makes estimate for the current design and supplies the reference for further design of the launch system.
