| Abstract: | Confused concepts and difficult problems usually could be found in the degree of freedom of mechanism calculation. Common formula changes in the planar freedom degree mechanism calculation degree of freedom in planar mechanism, mechanism design formation principle and work characteristic of variable freedom degree mechanism were analyzed with the combination of some instances. The freedom degree calculation difficulties and various kinds of imposed constraints and formation change were investigated with an aim of offering help for correct understanding and freedom degree calculating, and providing an effective way to innovate excellent new mechanism and to avoid miscalculation. |
