| Abstract: | Objective To analyze the performance change of multilayered damping composite panels after five years of storage. Method The vibration attenuation performance of multilayered damping composite panels was researched after five years of storage at normal atmospheric temperature. Vibration attenuation performance and modality variation of multilayered damping composite panels before and after storage were obtained according to sine scanning test and random vibration before and after storage to carry out contrastive analysis. Results After five years of storage, radial modality of panels declined obviously. The normal modality had little change. The acceleration response on subassemblies had no change. Conclusion Multilayered damping composite panels also meet the performance requests after five years of storage. |
