Evolution of Constrained Layer Damping Using a Modified Cellular Automata Algorithm

摘要：

　　In order to improve the treatment efficiency of the constrained layer damping (CLD), it is meaningful to have a study on its layout optimization.This paper based on current research of Cellular Automata (CA) algorithm for CLD optimization, points out that the current application of CA algorithm is less efficient, considering that adding or deleting a single CLD patch almost does no change to the entire structure, then makes a simplification and modification of CA algorithm.With the aim at improving the structural modal loss factor, this paper uses the current CA algorithm and its modified algorithm to optimize a partial CLD plate.The results have shown that the modified CA algorithm for CLD optimization can not only substantially increase computing efficiency, but to some extent, improve the optimization effectiveness.
