Appling the theory of machines and mechanisms

a mathematical model was established for the design of a typical gear-linkage combined mechanism. In the course of solving the mathematical model

a design procedure named interactive design of graphic simulation was proposed

which use three-dimensional graphic simulation to watch and analyze the overall property and the distribution of its solution

and then use two-dimensional graphic simulation to search out its local solution. Finally

it was pointed out by an example that the procedure can not only unify logical thinking and thinking in image

but also unify overall solution and local solution.
