By CAD, based on diagrammatize principle, the dimensions of every parts in cracker rocker mechanism under different conditions are determined, and design demands are satisfied.
A new training apparatus for legs based on crank and rocker mechanism,is proposed in this paper.It can simulate the to-and-fro motion of the sporter's legs realistically.
