| 目的 分析多层阻尼复合板常温贮存5年的性能变化。方法 对多层阻尼复合板进行常温下贮存5年的减振性能研究，通过贮存前后的正弦扫描试验和随机振动试验，获得贮存前后多层阻尼复合板的减振性能和模态变化，进行对比分析。结果 阻尼复合板常温贮存5年后，径向模态有较大的下降，法向模态变化较少，组件上的加速度响应基本无变化。结论 该多层阻尼复合板常温贮存5年后仍然满足要求。 |

| 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. |
