| 中文摘要: |
| 目的 分析航天飞行器结构各部分输入能量对振动的贡献量。方法 将基于能量的传递路径分析方法引入航天飞行器舱段结构的声振响应分析中，通过声振响应分析获得结构的振动响应后，进一步得到结构各部分的能量分布以及输入能量，计算得到各部分输入能量的贡献量。结果 对于本文中的舱段结构，仪器支架安装壁板的能量主要来源于外部噪声激励，与之相连的蒙皮结构也会对其有输入能量，但贡献量不大，约占10%。仪器支架底部的能量主要由安装位置处的蒙皮贡献，相邻蒙皮贡献的能量约占20%。仪器设备安装处的能量，主要由仪器支架贡献。结论 形成的舱段结构声振响应能量传递分析方法，可为结构的传递路径分析、结构优化设计、减振降噪设计奠定基础。 |

| The work aims to analyze the contribution of input energy from various parts of spacecraft structure to vibration. The energy transfer path analysis method was introduced into an acoustic vibration response analysis. After obtaining the vibration response of the structure, the energy distribution and input energy of each part of the structure were further obtained, and the contribution of the input energy of each part was calculated. For the cabin structure in this paper, the energy of panels installing the instrument bracket was mainly contributed by external noise excitation, and the skin structure connected to it also had input energy, but the contribution was not significant, accounting for about 10%. The energy at the bottom of the instrument bracket was mainly contributed by the skin at the installation position, with adjacent skin contributing about 20% of the energy. The energy of structure installing the instrument equipment was mainly contributed by the instrument bracket. In conclusion, the energy transfer analysis method for acoustic and vibration response of cabin structures can provide support for the analysis of transmission paths, structural optimization design, and vibration and noise reduction design of structures. |
