Summary:The invention discloses an acoustic model equivalent method of a hollow aluminum profile. The method comprises the following steps: the sandwich layer of the hollow aluminum profile is equivalent to aviscoelastic material layer; the sandwich layer is arranged between the upper panel and the lower panel of the hollow aluminum profile to form an acoustic model of a three-layer composite structure;Wherein the geometrical structure and physical properties of the upper panel and the lower panel are unchanged; The equivalent parameters of the viscoelastic material layer are obtained according to the related parameters of the interlayer. The invention provides an acoustic model equivalence method for hollow aluminum profiles, The sandwich of hollow aluminum profile is equivalent to viscoelasticmaterial layer, which is arranged on the upper and lower panels of the hollow aluminum profile to form an acoustic model of three-layer composite structure. According to the related parameters of thesandwich, the equivalent pa
