| Abstract: | The mode localization phenomena of disordered symmetrical Structures of airplanes con-sisting of carriages is investigated. Emphais is placed on the formulating of criterion that predicts the occurrence of mode localization in symmetrical structure with one side stiffness peturbation. Criterion and the numerical results are compared in detail and excellent argree-ment is found. We can refer to the criterion when design symmeterical structures of air-planeds. |
