The space model and dimensional types of the four-bar mechanism

摘要: Abstract In this work, a space model in the form of an oblique obtahedron is constructed and shown to represent all dimensional types four-bar mechanism. The divided into eight subregions which are equivalent groups mechanisms. Moreover 48 small regions can be obtained contain kinds type for general Taking intersections occuring within model, series hexagonal plane configurations obtained. character diagrams mechanism plotted on these configurations. This work helps designers realize relationships between characteristics link lengths mechanisms, hence improves synthesis method
