实现给定轨迹的平面四杆机构设计的CAD方法

CAD method to realize the design of plane four-rod organ on designated track

实现给定轨迹的四杆机构设计,是平面四杆机构设计的基本问题。实现给定轨迹的平面四杆机构设计的CAD方法,是将连杆机构原理与计算机绘图相结合,编制了成组连杆曲线绘制程序。并对绘制连杆曲线的原理进行了充分地分析和论证。利用程序绘制的“电子连杆曲线图谱”,可方便地在计算机上进行“实现给定轨迹的平面四杆机构设计”。

It is a basic question in the design of plane four- rod organ to realize the design of the four- rod organ on the designated track. The CAD method to realize the plane four- rod organ on the designated track is a combination of connecting rod and CPD. This method can work out drawing programmes for collective rod curves. This paper fully analyses and demonstrates the principle of drawing the connecting rod curve. The application of programme - written electronic connecting rod curve collective drawing makes it easy to realize the design of the plane four- rod organ on designated track on computers.
