摘要
针对机载武器传递对准中杆臂效应动态补偿这一技术难题,提出了一种改进的杆臂效应动态补偿方法。通过建立机翼的挠曲模型,得到挠曲变形作用下的标称动态杆臂矢量;结合动态杆臂,详细分析了杆臂效应的动态补偿机理;采用"速度+姿态"匹配传递对准模型对所提方法进行了分析与验证。仿真结果表明,所提方法能够有效解决杆臂效应的动态补偿问题。
In order to solve the technical problem that the dynamic compensation for lever arm effect in transfer alignment of airborne weapon,an improved dynamic compensation method for lever arm effect was proposed.Firstly,through the establishment of the flexure model of wing,the nominal dynamic lever arm vector under flexural deformation was obtained.Then,combining with the dynamic lever arm,the dynamic compensation mechanism of lever arm effect was analyzed in detail.Finally,the proposed method was analyzed and validated by using the "velocity plus attitude" matching transfer alignment model.The simulation results show that the proposed method can effectively solve the dynamic compensation problem of lever arm effect.
