哈尔滨工业大学本科毕业设计( 论文)I摘要研究液晶光学相控阵在跟踪/瞄准捕获（APT）技术中的应用时，需要在跟瞄系统远场竖直平面内为系统提供一个随机可控的模拟目标，这种随机可控模拟目标装置是典型的机电一体化装置。本文主要对装置的机械结构进行了研究和设计，提出了 5 种装置的机构构型，重点分析了其中两种构型。使用MATLAB 对这两种构型进行了运动学计算，对运算的结果进行了定性比较，选取“仿极坐标”构型为装置的机构构型。在对装置进行机械设计时，把装置分为了直线运动单元和转动单元，分别设计。在对直线运动单元进行设计时，通过比较各种形式的导轨和传动方式，选择了线性滑块导轨和同步带传动来实现直线运动单元。最终利用 SolidWorks2008 对整个装置进行了三维设计及受力仿真分析。关键词：随机可控；模拟目标装置；运动学计算；同步带传动；受力仿真分析哈尔滨工业大学本科毕业设计( 论文)IIAbstractIn the research of liquid crystal optical phased array applied in the tracking / target acquisition (APT) technology, a controlled simulation of random targets, which were controlled device is a simulated target A typical mechatronic devices is needed in the vertical plane of the far-field Tracking System. In this paper, the primary interest is the research and design of the mechanical structure of the device, five kinds of device body configuration is proposed, and the paper mainly focuses on analysis of the robotic arm configuration and imitation polar configuration. Using MATLAB to finish the kinematics calculations of these two configurations, compares the results of the calculations qualitatively, selects the imitation polar configuration for the devices body configuration. In the mechanical design of the device, the device is divided into a linear motion unit and rotation unit, and is designed respectively. In the design of Linear motion unit, by comparing the various forms of rail and transmission mode, a linear slide rails and drive to achieve synchronous linear motor unit is chose. Finally, the whole device is performed the three-dimensional design and simulation analysis of the force by using SolidWorks2008.Keywords: Randomized controlled; Simulated target device; Kinematics calculation; belt drive; Force Simulation and Analysis哈尔滨工业大学本科毕业设计( 论文)III目录摘要 .IAbstract.II第 1 章 绪论 .31.1 课题研究背景 .31.2 课题研究内容及意义 .3第 2 章 系统设计的基本知识 .32.1 跟瞄系统介绍 .32.2 跟瞄实验系统 .3第 3 章 方案优选 .33.1 设计目标 .33.2 提出多种方案 .33.3 方案论证 .33.3.1 方案 4 的运动学分析 .33.2.2 方案 5 的运动学分析 .33.2.3 定性比较 .33.4 本章小结 .3第 4 章 机械设计及仿真 .34.1 总体设计 .34.1.1 直线运动单元实现方案 .34.1.2 转动单元实现方案 .34.1.3 驱动类型选择 .34.2 直线运动单元设计 .34.2.1 同步带及带轮设计 .34.2.2 线性滑块导轨设计 .34.2.4 SolidWorks 设计及仿真 .34.3 转动单元设计 .34.3.1 建立约束方程 .34.3.2 摇臂设计 .34.3.3 减速器设计 .34.3.4 SolidWorks 设计及仿真 .34.4 本章小结 .3结论 .3参考文献 .
