Analysis of effects of anisotropic parameters on the loss factor of anisotropic laminated damped thin plates

The effects on the loss factor of anisotropic laminated damped thin plates produced by changing its anisotropic parameters were studied by using methods of orthogonal experiments and theories of anisotropic laminated damped structure.As the results show,the effects of anisotropic parameters on the loss factor of the thin plates are different under the different molds,in which the influence of the fibrous paving angle is complicated to the loss factor of thin plates for its influence changing largely from the mold or the construction of thin plates,and the influence of the shear modulus in longitudinal or transverse direction or the Young's modulus in longitudinal or transverse direction goes up to enlarge gradually along with the mold.In addition,the further analysis of the effects of anisotropic parameters on the loss factor shows that the effects of anisotropic parameters on the loss factor have different characteristics,and the optimal-design of the loss factor has potential for the way of construction design.
