| 摘 要： | 针对火箭滑橇轨道准直度精密测量任务,该文分析了工程建设初期利用传统控制网布设方案存在的缺陷与不足,并提出了三级轨道控制网设计思想。首先选择高精度的一级控制网点,然后将控制网由原来的直线等距布设调整为面域均匀布设,最后将控制网布设方式由直线布设调整为东西对称布设,建立了高速轨道平面控制网的精度估算模型,分析了优化控制网的网点精度。结果表明:改进布网方式能够较好地实现对横、纵两个方向的精度控制。

| Abstract: | Aiming at the task of measuring rocket sled track alignment precision,defects and shortcomings of traditional control network were analyzed,which built in the beginning of the construction,a new method named three level track control network for optimizing the original control network was designed.The higher precision control points were selected,first,and then the net of original line and distance distribution was changed to the uniform plane layout,at last the line layout to the symmetrical was adjusted,the accuracy of the points of the three level track control network was analyzed,the results showed that this method could realize better accuracy control in horizontal and vertical direction. |
