扫描线转动机构 - 8 . we demonstrate a mechanism " design example of a 2 - dof rotating mechanism . it incarnates our research work on mechanism design and mechanism analysis
8 、通过一种二自山度转动机构的设计，体现了本文在机构综合、机构分析人仰所做的工作。 - After analyzing the existing ambiguity resolution methods the dissertation investigates the baseline rotation method based on the antenna - swap idea , and develops the fixed axis rotation maximum - minimum method ? farmm and the equivalent rotation maximum - minimum method ? ermm applicable for static basement and moving vehicle respectively . the former lowers the demands on rotation device while the latter improves the flexibility of antennae installation . meanwhile the dissertation also brings forward an ambiguity function search method which needs only one single epoch data with the outer aided information , and investigates the accuracy requirements for the assistant pointing information
其次,通过与gps等多星系统定向关键技术的对比分析,指出双星定向模糊度确定的难度;在分析现有模糊度求解方法的基础之上,研究了基于交换天线思想的转动基线模糊度确定方法,并提出了适合于静基座的定轴转动极大/极小值farmm法,以及适合于地面运动载体的等效转动极大/极小值ermm法,前者降低了对转动机构的要求,后者则提高了天线安装的灵活性;同时,提出了一种借助外部辅助信息的模糊度函数搜索法实现单历元双星定向,并分析了对外部辅助单轴姿态信息的精度要求。 - Firstly , the structures analysis of the optical synthetic aperture principle demonstration prototype has been introduced . on the basis of these , has modeled the three dimension modeling of this system , analyzed the force of the segment mirror ’ s rotational mechanism and rigid - flexible coupling dynamics simulation . thirdly , analyzed the key parts of the system by making use of the finite element soft
首先,本文对光学合成孔径原理演示样机装调机构进行了结构分析;其次,建立了光学合成孔径原理演示样机三维模型,并对子镜二维转动机构进行了受力分析及刚柔耦合动力学仿真;最后,结合理论分析、动力学仿真及实验研究,对演示样机不足之处设计改进方案并进行仿真分析。 - The contacted method leaded to wear of sensors and affected the stability of result , thus main tenance became more difficult . . the non - contacted method used laser displacement sensor to scan the object . it was difficult to measure different geometrical profiles of the wheel set flange because the optical axis should be vertical to the surface of flange
非接触测量方法是采用激光位移传感器进行扫描测量，由于不同轮对踏面轮缘部分的磨耗不同且形状不一，扫描转动机构难以保证激光位移传感器光轴与轮缘表面较垂直，这会带来较大的测量误差，而且扫描转动机构结构较复杂。
