Abstract

The global dynamic behavior of the elastic impact system with one random parameter is researched in this paper. First, based on the orthogonal polynomial approximation, the stochastic system is transformed into an equivalent deterministic system. Then the composite cell coordinate system method is used to derive the basins and attractors of the equivalent system. It is found that the random parameter affects the global dynamics of the system tremendously. Under the same conditions, the basins and attractors of the stochastic system are entirely different from that of the deterministic system.
