【摘要】：机构是力和运动的传递和生成的机械装置,现在以多种形态大量应用于生产现场。本文所研究的六杆机构是为了使四杆机构可以在平面上做最短路径的往复运动,在四杆机构驱动杆上设计Dyad (Crank-rocker机构)的装置。这种六杆机构以多种设计形式广泛应用于生产现场。随着自动化产业的发展,运用电动马达和机构来完成生产现场装配已经成为一个重要的研究方向。本文对经过预定三位置的六杆机构设计方法及六杆机构转动时出现的几点问题(顺序问题、转移问题)的解决方法进行了研究,基于以上的研究结果,设计研发了经过预定三位置的四、六杆机构设计模拟软件(windows用)。主要研究内容如下：首先,对基于三位置的四杆机构进行了综合分析,并进行了相关研究：(1)已知被驱动杆上转动点位置坐标时,计算固定点的位置坐标；(2)已知被驱动杆上固定点位置坐标时,计算转动点的位置坐标；(3)通过数学公式推导,计算出Pole和image pole位置的坐标；(4)在转动点运动区域,通过菲莱蒙结构,计算出被驱动杆转动点不可以选择的区域,从而解决转移问题；(5)在固定点运动区域,通过菲莱蒙结构,计算出被驱动杆固定点不可以选择的区域,从而解决转移问题；(6)通过数学公式推导,计算出转动点作直线运动的条件。其次,对Dyad机构(Crank-rocker机构)进行了综合分析。(1)在被驱动杆上连接Dyad机构,使四杆机构可以在平面上做最短路径的往复运动,这就要求Dyad机构必须保证曲柄的存在。本文运用著名的格拉斯霍夫准则(Grashof type)计算出Dyad机构的曲柄存在的条件；(2)设计Dyad机构时,转移问题的解决方法。最后,以C++、MFC、OpenGL为编辑语言,设计研发经过预定三位置的四、六杆机构设计模拟软件,实现图形建模、参数设定、可视化仿真。
[Abstract]:The mechanism is a mechanical device for the transmission and generation of force and motion, and is now widely used in production sites in a variety of forms. In this paper, the six-bar mechanism is designed to make the four-bar mechanism perform the reciprocating motion of the shortest path on the plane, and the device of Dyad (Crank-rocker mechanism) is designed on the driving rod of the four-bar mechanism. This six-bar mechanism is widely used in production site with various design forms. With the development of automation industry, it has become an important research direction to use electric motor and mechanism to complete production site assembly. In this paper, the design method of six-bar mechanism with predetermined three positions and the solutions of several problems (order problem, transfer problem) that appear when the six-bar mechanism rotates are studied. Based on the above research results, Design and development of four and six bar mechanism design simulation software (windows) after a predetermined three position. The main research contents are as follows: firstly, the four-bar mechanism based on three positions is synthetically analyzed, and related studies are carried out: (1) when the position coordinates of the rotation point on the driven rod are known, the position coordinates of the fixed points are calculated; (2) when the position coordinates of fixed points on the driven rod are known, the position coordinates of rotation points are calculated; (3) the coordinates of Pole and image pole positions are derived by mathematical formula; (4) the coordinates of pole and image pole positions are calculated through the Filemon structure in the moving region of the point of rotation. In order to solve the problem of transfer, the region that can not be selected by driving rod rotation point can be calculated by Filemon structure, and the problem of transfer can be solved by calculating the region that can not be selected by driving rod rotation point. (5) in the moving region of fixed point, the region that can not be selected by driving rod fixed point can be calculated by Filemon structure. (6) by deducing the mathematical formula, the conditions for the rotation point to move in a straight line are calculated. Secondly, the comprehensive analysis of Dyad mechanism (Crank-rocker mechanism) is carried out. (1) connecting Dyad mechanism on the driven rod, the four-bar mechanism can make the reciprocating motion of the shortest path on the plane, which requires the existence of crank in Dyad mechanism. In this paper, the existence conditions of the crank of Dyad mechanism are calculated by using the famous Grashof type criterion. (2) the solution of the transfer problem in the design of the Dyad mechanism. Finally, using C / MFCU OpenGL as editing language, the software of design simulation of four-and-six-bar mechanism is designed and developed, which can realize graphic modeling, parameter setting and visual simulation.
