The Research of Mechanism Synthesis Based on Mechanical System Chaos Anti-control Methods

摘要

Many questions in natural science and engineering are usually transformed into solving nonlinear equation. Newton iterative method is an important technique to one dimensional and multidimensional variables and iterative process exhibits sensitive dependence on initial guess points. For first time, the nonlinear feedback chaos anti-control method of mechanism synthesis was put forward. The motion of mechanical centrifugal governor systems was transformed from periodic motion to chaotic motions by the addition of nonlinear feedback and all solutions of the nonlinear questions of mechanism synthesis were found by utilizing chaotic sequences of chaotic motions of mechanical 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.
