一种雷达天线翻转机构的设计

摘要

为了满足天线自动展开与快速撤收的要求，设计了一种天线翻转机构。重点阐述了该机构的工作原理、结构设计、力学分析及其相应的校核计算。结果表明，该机构性能稳定，天线重复精度高，达到了技术指标要求。%Radar antenna turnover mechanism is designed to meet the requirements of auto-expansion and fast retraction of anten￣na. Its operating principle,structure design, mechanics analysis and responding check calculation are stated in this thesis. The re￣sults show that the steady performance and repeatability accuracy of the antenna is absolutely with in the reach of its technical qualifi￣cation.
