一种基于非线性回归的载人航天器密封舱内在轨噪声分析方法
A analysis method of on-orbit noise in manned spacecraft pressurized cabin based on non-linear regression
摘要
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.关键词
