摘要: 针对弹道修正弹药出炮口后滚转角处于随机状态,捷联惯导系统(SINS)失准角过大时卡尔曼滤波收敛困难的问题,提出在卫星拒止环境下利用神经网络快速估计初始滚转角的改进方法。在炮口处布设少量导航信标,建立反向传播(BP)神经网络拟合初始滚转角与观测量间的非线性映射模型。针对信标辅助下姿态弱可观的问题,引入 ...

摘要: 航空发动机叶片、机匣等复合材料结构内部纱线在纤维预制体赋形过程中,纤维束间会发生挤压、错动、扭转等相互作用,使得经纬纱线截面形态、体积含量和走向轨迹呈现不规则分布,这种复合材料细观结构的高度非均匀性极易引起材料内部应力集中,导致损伤发生,降低结构的可靠性,同时也大大增加了复合材料结构力学性能分析与评 ...
