摘 要

通过在VC/MFC上进行编程，将机构简图的绘制，四杆机构、齿轮机构和凸轮机构的运行规律进行编程。根据基础知识，在简图绘制界面要完成直线、折线等功能的，并且具备保存机构简图的功能；四杆机构的杆可以简化成直线，通过四杆机构运动规律函数进行编程，输出四杆机构精确的运动规律；齿轮范成机构模型的建立，依靠基本参数的设置，绘制出基本的轮廓，并进行齿轮的范成运动；凸轮机构的多个运动规律，分别进行不同的函数编程，实现其运动规律的变化并输出相应的运动规律变化曲线。在这些基础上完成界面的优化和功能的多样化，达到一个更加完善的仿真软件，让使用者能够从中学到更多。

通过本次设计，要最终完成一个单独的模块，可以在这个单独的模块上实现以上四个功能。通过这个研究，在学习中能够有效的认识典型机构，在实验中更加多元化的进行学习，同时也更加深入的了解和学习典型机构运动规律虚拟仿真的意义和重要性。

Abstract： Virtual simulation research on typical mechanism motion is currently very popular topic. With the development of science and technology, shortage of resources, the cost of experiment is too big, in the colleges and universities teaching, some problems about typical mechanism motion law of experiment, it’s necessary to need a virtual simulation experiment on computer software. Through this topic research, can create a convenient software, students can understand typical mechanism motion rule can easily and quickly, can be in the process of experiments combined with the virtual simulation, a more thorough understanding of typical mechanism motion. This subject is a development, do not rely on other platforms, but also set up a corresponding model library, realize the accuracy of motion law.

Through the VC and MFC programming, the agency schematic drawing, four-bar mechanism, gear mechanism and programming operation rule of the CAM mechanism. According to the basic knowledge, in the schematic drawing interface to complete the line, line, etc, and have saved organization diagram function; Four-bar linkage rod can be simplified into a straight line, through the motion law of four bar linkage function programming, the output precision of four bar linkage motion; Gear of selecting such assignment model, depending on the basic parameter Settings, draw the outline of the basic, and sports gear of selecting such assignment; CAM mechanism of multiple motion law, respectively in different functional programming, realize the motion law of change and output the corresponding motion curve. On the basis of the complete optimization of the interface and function diversity, to achieve a better simulation software, let users can learn more from it.

Through the design, to finally complete a separate module, on this single module can realize the above four function. Through this research, can effectively recognize typical institutions in the study, more diversity in the experiment study, at the same time also more deeply understand and study the typical mechanism motion regularity of the meaning and importance of virtual simulation.
