1、 摘 要 三轴雷达仿真转台是三轴转台的一种，本次设计的三轴雷达仿真转台主要用于 某型机载雷达的测试。转台性能的优劣直接关系到仿真和测试试验的可靠性，是 保证某型机载雷达的精度和性能的基础。本文针对三轴雷达仿真转台的机械结构 设计进行了详细的讨论，并进行了理论论证及必要的计算，同时对本转台中使用 到的测量元件及联轴器等其他原件的结构及原理作了简单的介绍，设计中采用铸 铝合金作为台体的材料，实现了低转速、高精度的要求，并且减轻了整体的重量， 使机构在满足：转角范围、速度范围、最大角加速度等设计参数要求的前提下， 使结构设计尽量优化。本设计紧紧围绕着设计任务书中的各项指标，从内环开始 至外环一步一步

2、地展开设计。本文主要内容包括转台的总体结构论证、转台的详 细结构设计、转台的误差分析等。结合转台设计的特点，本文重点讨论了转台机 械结构的设计思想及设计过程。 关键词：三轴仿真转台；机载雷达；测量元件；联轴器：内环：中环：外环。 2 ABSTRACT Three shafts radar simulation turntable is one type of the three shafts turntable . The three shafts radar simulation turntable in this design is mainly used to test a certai

3、n type of airborne radar. The simulation turntable has great influence on the reliability and credence of experimentation,so the precision accuracy of a certain type of airborne radar is based on simulation turntable.This paper discusses detailedly the design of mechanical structure of the three sha

4、fts radar simulation turntable . Then uses the principle to demonstrate it and do the necessary calculation . At the same time, introduce the principle and structure of measurement components and clutch and other components used in the turntable in brief . This design closely revolves around every targets in design assignment,and spreads out from inner frame to outer frame step by step. The chief content of this paper involves the demonstration of the general structure , the design of the de
