The problems of mechanism synthesis and approximate synthesis can be transformed into nonlinear equations to be found.Newton iterative method is an important technique to one dimensional and multidimensional variable and iterative process exhibits sensitive dependence on initial guess points

but only one solution can be found.Combining Newton iterative method and chaotic sequences

based on chaotic motion of new chaotic system advanced by Liu lately

a novel method of mechanism synthesis was put forward.All solutions of the nonlinear questions of mechanism synthesis were found by utilizing chaotic sequences of chaotic motion of new chaotic system to obtain locate initial points.As an example the problem of function generation for planar four-linkage guide mechanism was considered.This makes that multi-projects selecting could be possible.This method is adaptive to planar multi-linkage and spatial mechanism.This provides a new simple realization method for mechanics design.
