| 中文摘要: |
| 分析了引起某空间相机指向反射镜面形误差的载荷,运用有限元分析软件对指向反射镜在几种典型载荷作用下产生的镜面变形进行了多场耦合仿真,计算结果表明该指向反射镜完全满足光学系统的性能要求,从而为相机设计提供了有力依据。 |
| 英文摘要: |
| Loads which causes surface contour deflection of the directional mirror of space camera have been analyzed.Coupled-field analysis to obtain deflection value of mirror surface contour under the circumstances of different load are performed using finite element analysis software.The calculating results indicate that the directional mirror satisfies performance requirements of optical system completely,providing excellent evidence for the camera design. |
