The Analysis of Fiber Positioning System Temperature

Abstract:

The LAMOST fiber positioning system is installed in focal panel. Thermal deformation influences focal panel and fiber positioning precision greatly. The heat transfer mathematical model of focal panel is established with the analysis of the focal panel structure. A single step motor heat under the normal work is detected. By using finite element analysis software Ansys the temperature distribution of the focal panel is calculated, which provides the basis for the next step calculation of the focal panel thermal deformation.
