Computer aided design, Computer graphics
The synthesis of planar and spatial mechanisms is often accomplished by either trial and error supplemented by computer analysis or by specific analytical techniques in the literature. In either case it is extremely helpful to be able to visualize a physical design as it emerges, and to see a graphic display of it in animated motion. This paper describes the development of a general interactive program for both analyzing and viewing a spatial 4-bar (RSSR) mechanism in animated motion. The analysis provides complete position, velocity, and acceleration information and, for the special case of the planar 4-bar, the same information is available for an arbitrary coupler point. The animation, while not real time, is sufficiently fast to provide the designer with a physical feel for the relative movement of the links. The program is written in interactive BASIC and is designed to run on a standard Apple II microcomputer. The result is a helpful tool for the mechanisms designer, and an example is presented to demonstrate the program's flexibility.
