四杆、凸轮和齿轮机构CAI软件的设计

CAI software design

所研究的 CAI软件使用 PowerPoint97制作了大量的教学用幻灯片，用于 展示教学的文字内容 .用 Visual Basic6.0语言设计主控模块、动画演示和动态的设计练习 .主控模块下设置三个子工程，即四杆机构、凸轮机构和齿轮机构；各个模块下各自分别挂 接教学模块和练习模块两个下级模块 .三个模块之间相互独立，可以一起使用，也可以分别 使用 .该软件既可用于教学，也可用于学生自学 .

The CAI software presented in this paper,which is composed of a lot of slides deding with teaching contents on four bars mechanism,cam mechanism and gear mechanism was constructed with PowerPiont97 software. The main controll ing block, animating block and exercise block were designed by Visual Basic 6.0 Language. Three subprogram are included in the main controlling block:four bars mechanism,cam mechanism and gear mechanism. Two junior blocks are attached to e ach subprogram: teaching block and exercise block. Three subprograms are self－ governed. The user could not only use them together, but also use them individua lly. This software can be used by directors for teaching and also by students for self－ teaching.
