Abstract

With the advancement of space technology, satellites are assuming an increasingly pivotal role in various fields. Currently, satellite structures incorporate a growing number of thin-walled parts. During the assembly process, the movement and connection of these parts are prone to generating assembly deviations, which seriously affects the overall assembly quality of the satellites. In order to accurately predict assembly deviations before assembly, this paper introduced an assembly deviation analysis model which took rigid and flexible properties into account. Starting from the attitude adjustment of satellite assembly, the transmission law of manufacturing error was established. Then, the assembly deviation analysis model integrating rigid and flexible properties was established. Finally, the assembly experiment was carried out to verify the effectiveness of the proposed model. The results showed that the average absolute error between the measurement results and calculation results was only 0.032 mm and the maximum absolute error was 0.074 mm. The average solving accuracy of the assembly deviation was 94%. The result fully proved the effectiveness of the proposed model.

结合刚柔特性的卫星柔性部件的装配偏差分析：建模与实验

随着空间技术的发展，卫星在各个领域发挥着越来越重要的作用。目前，卫星结构中的薄壁部件越来越多。在装配过程中，这些零件的移动和连接容易产生装配偏差，严重影响卫星的整体装配质量。为了在组装前准确预测组装偏差，本文引入了一种考虑刚柔特性的组装偏差分析模型。从卫星装配的姿态调整入手，建立了制造误差的传递规律。然后，建立了刚柔结合的装配偏差分析模型。最后，通过装配实验验证了所提模型的有效性。结果表明，测量结果与计算结果之间的平均绝对误差仅为 0.032 毫米，最大绝对误差为 0.074 毫米。装配偏差的平均求解精度为 94%。这一结果充分证明了所提模型的有效性。
