Effective forecast of circular error probability in underwater robots
, 2012 在水下机器人设计过程中,对于导航精度设计指标无法用物理实验进行验证。如何有效预报圆概率偏差(CEP)成为了亟待解决的问题。采用直线航路模型,对误差源在直线航路上引起的导航误差进行定量分析,推求各误差合成后的纵向误差和横向误差表达式,建立水下机器人圆概率偏差迭代方程,求得圆概率偏差预报结果。推导结果表明横、纵误差之比小于0.7时可保证圆概率偏差不大于前两者之中的大者。该方法与实际实验结果吻合,表明提出的导航误差分析和圆概率估算方法是有效的 ...

Jianzhu Gangjiegou Jinzhan为研究大跨度连续钢桁梁桥施工阶段的受力情况，对连续钢桁梁桥的竖向变形和关键节点应力进行了现场实测。依据变形协调原理，建立了节点实体与杆系相结合的多尺度数值分析模型，获得了桥梁成桥阶段的结构整体内力和局部节点受力情况，将桁杆变形和应力测试值与有限元计算值进行了对比分析。结果表明，下弦杆竖向最大变形值小于6 cm，与计算跨径之比小于1/2 300。杆件实测应力最大值为32 MPa，位于E8节点下弦杆附近。最大变形值和应力值均满足设计规定要求。下弦杆竖向变形实测值与计算值变化趋势基本一致，两者差值小于10 ...
