Abstract:

The problem discussed here is the research work of linkage mechanisms, which has relations with geometry. These works include planar and spatial mechanisms, series and parallel mechanisms, geometrical modeling of the mechanisms and equations solving. The kinematic analysis and synthesis of mechanisms are also discussed. Except traditional method, modern ones for solving these problems are outlined here. When computer is used, some special problems appear in the calculation and are also discussed.

Key words: linkage mechanisms, geometry algebra, kinematic analysis and synthesis, unknown elimination
