Interactive Analysis of Planar Mechanisms on a Small Computer 770544

A new, simple approach to general planar mechanism analysis has been developed which is intended for use with interactive graphic display terminals. This approach can be applied to 80 percent of the mechanisms used in earthmoving equipment. It allows even complex machanisms with multiple external loadings to be analyzed quickly, in small amounts of core.This paper describes the method for modeling a mechanism and the procedure for finding its new positions. Velocity, acceleration, and static force analysis techniques are presented and illustrated by example mechanisms. Not only are these procedures basic and logical, they are also repetitive from pin to pin on the linkage, which makes them easy to program.
