高速旋转弹丸弹道修正原理分析及仿真

解决由于高速旋转弹丸的旋转特性导致难以采用常规方案对其进行弹道修正的技术难点.提出基于压电陶瓷智能材料的弹道修正原理技术方案,依据弹头可能动作的思路,设计弹头修正机构,通过探知弹头旋转频率,以此调整压电陶瓷杆的加电模式,利用压电陶瓷的逆压电效应,从而调整相应陶瓷杆的伸缩动作,保证在旋转条件下弹头可以向固定方向偏转,解决了修正旋转弹丸的难题.详细阐述了修正弹丸的系统组成和工作原理,同时建立了修正弹丸理想条件下的外弹道数学模型,并通过仿真计算得到一定条件下修正弹丸的弹道曲线和详细修正数据,仿真结果验证了该方案的有效性和可行性.

Trajectory Correction Principle Analysis and Simulation Research of High-speed Rotating Projectile

It is very difficult to make trajectory correction for high-speed rotating projectile because of rotating characteristic,which can not be solved by adopting the traditional correction projects.Aimed at this technology nodus,a new type of trajectory correction technology project is presented based on piezoelectricity pottery intelligent material.According to the idea that the warhead can act,the warhead correction mechanism is designed.The adding electricity mode of piezoelectricity pottery pole is regulated...
