| 摘 要： | 文章提出一种载人航天器密封舱内噪声非线性回归通用分析方法,可基于地面噪声试验测得的数量较多的数据样本和在轨噪声测试获取的少量数据样本,建立密封舱内位置–在轨噪声的数学模型。经验证该模型能够较为准确地拟合密封舱内在轨噪声水平,从而为开展载人航天器的降噪设计、优化噪声仿真模型和验证降噪措施效果提供数据支持。

| Abstract: | The noise inside a manned spacecraft pressurized cabin in orbit is an important issue for astronauts. In this paper, a non-linear regression analysis method for the noise in the manned spacecraft pressurized cabin is proposed. From the noise data of a manned spacecraft pressurized cabin, the on-orbit position-noise math model is built by this method. It is shown that the noise deviation between the value calculated by the on-orbit math model and the value measured by test is less than 4%. The model could offer predicted on-orbit noise data for the noise reduction design, the noise simulation and the noise reduction measure verification on the ground stage. |
