空间平面反射镜组件销钉预紧的非线性分析

介绍了产生结构非线性的主要来源与接触理论，对平面反射镜组件建立了合理的有限元模型.利用接触非线性分析方法分析了小重锤(m=0.18kg)在不同下落高度冲击销钉而对锥孔造成的法向压力；随后，将不同锥孔法向压力对镜面面形精度的影响进行了非线性和线性分析；然后，进行了空间平面反射镜的成像实验.分析与实验结果表明：采用非线性分析得到的面形精度比线性分析更接近实验值，非线性分析与实验值之间的最大误差为8.6%.由此对该空间平面反射镜组件提出了合理的销钉预紧方案，即小重锤最大自由下落高度不超过25mm.

Abstract

The main contact sources and theory were introduced, and the reasonable finite element model was established. The nonlinear contact analysis method was used to analyze a small hammer (m=0.18 kg) with different height impacting pin, and the pressures applied to coneshape bores were obtained. Subsequently, the surface shape accuracy of the planar mirror was analyzed with both nonlinear and linear analysis methods. Then, the imaging experiment of the space plane mirror was carried out. The results of analysis and experiment indicate that the surface accuracy of nonlinear analysis is closer to experimental value than that of linear analysis, and the error of results between nonlinear analysis and experiment is 8.6%. Finally, one reasonable pin preload project of the space plane mirror assembly was proposed that small hammer maximum free fall height should not be larger than 25mm.
