On the basis of different random disturbance on the Body Centered Cubic(BCC)point set,the Voronoi random models for closed-foam are established.The topological properties and geometrical properties of the model are analyzed by statistical method and compared with those properties of Voronoi random model which based on the random point set.The statistical results indicate that the model tends to be irregular with the increase of random degree,and the topological properties of the model tends to be the same with those properties of Voronoi random model which based on random point set at higher random degree.Then,the distribution of wall number and cell volume could be described by lognormal distribution,and the binomial distribution is a good approximation to the strut number distribution.
