Vibration Propagation Characteristics of Binary Periodic Sandwich Panels

摘要：

　　By using the finite element method, the band structures of the periodic hollow cylinder sandwich panels are investigated, and the influences of the material and geometrical parameters on the band gap are discussed in detail.The results show that The Youngs modulus of panel and the coated layer have the greatest influences on the band gap of binary periodic hollow steel cylinder sandwich panels.The smaller the Youngs modulus, the lower the frequency band gap.The material and geometrical parameters of the core have important influences on the lower edges of the band gap.Thicker and higher hollow steel cylinder with large density is favorable to gain a wide low-frequency band gap.The work presented will provide a theoretical guidance in the vibration isolation research.
