Based on the method of Poincaré mapping under cell reference, we describe basins of attraction for coexisting multi-dimensional tori attractors in a three-degree-of-freedom vibro-impact system. Because the multi-dimensional tori attractors are very rare in the low-dimensional systems, we find that these coexisting tori attractors have positive measure basins in the sense of Milnor. The coexisting multi-dimensional tori attractors can be distinguished by the exactly Poincaré mapping and Lyapunov dimension. The basin of attraction can be estimated by the limit cycle in the Poincaré section from the viewpoint of engineering.
