基于MATLAB曲柄滑块机构运动仿真报告

1、*计算机仿真技术matlab报告*曲柄滑块机构目录一、基于GUI的曲柄滑块机构运动仿真二、基于simulink的曲柄滑块机构运动仿真曲柄滑块机构1.题目描述题目：对如图1所示的曲柄滑块机构的运动过程进行仿真，并用动画的方式显示曲柄滑块机构的运动过程，位移曲线、速度曲线和加速度曲线。图中，AB长R2，BC长R3mm，A点为坐标原点。 图1 曲柄滑块机构示意图2.实现方法利用GUI界面设计来对曲柄滑块机构的运动过程进行仿真，并用动画的方式显示曲柄滑块机构的运动过程。3.界面设计1. Gui 设计1）新建GUI：菜单-新建-gui，并保存为test52）界面设计：拖拽左侧图标到绘图区，创建GUI界面
