平面六杆机构的运动分析
摘要：本文档首先对平面四杆机构进行运动分析，再对平面六杆机构进行运动分析，进而分析了平面六杆机构的动力性能，最后运用运动仿真软件Visual Basic6.0对平面四杆机构和平面六杆机构进行运动模拟仿真。
  我们通过对平面四杆机构和平面六杆机构连杆的运动进行系统地深入分析，从而获得平面连杆机构运动性能，进而达到对平面连杆机构的动力性能分析的目的。为了使研究结果更加形象生动，我们运用Visual Basic6.0来模拟平面四杆机构和平面六杆机构的运动的过程，并且得出连杆的运动曲线图及其它相关结果。本文的主要特色是在各个设计进度中将会大量应用计算机高级语言Visual Basic编程来模拟平面四杆机构和六杆机构平面连杆机构的运动学分析的过程，包括建立运动约束方程和解方程两部分。模拟的原理是借助于连杆机构设计的解析法，利用时钟控件来循环改变直线或圆的坐标，实现动画仿真功能，同时我们可以进一步分析和检查平面连杆机构的位移、速度和加速度等运动特性的正确性。通过这些我们便可以得到平面连杆机构的力学性能，从而达到本文的目的。

The Dynamic Behavior Analysis of Planar Linkage
Abstract: This paper analyzes the motion of planar four-bar linkage at first, then it analyzes the motion of planar six-bar linkage. After that ,it does analysis of the dynamic performance of plane six-bar linkage. Finally, it simulates the campaign of planar four-bar linkage and plane six-bar agencies, using a simulation software -- visual basic 6.0.
   After systematically and analyzed plane four-bar and plane six-bar linkage in depth, we obtained the campaign performance of planar linkage mechanism. By this we achieved the purpose of analyzing the dynamic behavior of planar linkage mechanism. In order to make the study results more vivid and to obtain the linkage’s campaign curves and other related results ,we use visual basic 6.0 to simulate the campaign process of plane four-bar and plane six-bar linkage mechanism. The main special features in each design progress lieutenant general and will apply deluxe language Microsoft Visual Basic  of calculator in great quantities, to imitate planar four-bar linkage mechanism and planar six-bar linkage mechanism to get analytical process of the kinetics of the linkage mechanism, include the establishment move control formula and reach agreement formula two parts. Principle of imitate is ask for help from linkage mechanism design of resolution method, make use of clock to control a piece to come to circulating change straight line or sit a mark roundly, carry out an animation to imitate true function。 Meanwhile, we can further analyze and examine the correctness of planar linkage’s displacement, velocity and acceleration and other characteristics. Through these above we can get the mechanical properties of planar linkage, and so as to achieve the purpose of this paper.
