46、854885 (3)程序图总结通过此次机械原理课程设计，我学到了许多知识，在设计初级阶段学会了数学建模的基本方法，在这里很巧妙的利用复数的向量坐标法把几个点一一确定，然后利用有一个确定点能够确定其他的各个点的位置，于是就得到了我们所需要的从动点的位置和速度大小和加速度的大小。在动态图的设计中遇到了很多困难，又由于时间紧，所以没有达到自己的要求不过还是学到了很多东西，如利用tubo c的图形库函数来实现各种图形功能，虽然只是些简单的图形功能但是却让我学到很多。总之时间比较紧，许多知识又是现学的，因此在设计过程中，遇到过种种障碍，当然也认识到自己的不足，希望今后能在自己各个方面尤其是c语言编程方面能有所提高。参考文献机械原理 孙恒 陈作模C程序设计 谭浩强 计算机图形学 罗笑南 王若梅
