The Finite Element Model

This paper analyze the deformation of large aperture optical components under the thermal load based on the finite element model developed using the ANSYS software, which are used for inertia confinement fusion (ICF) experiments. High precision sensors are used to measure the temperature around the optical components in the target building and to form the temperature changing curve. The biggest temperature change is 0.3°C during 2 hours based on the measurement. The change is then loaded on the finite element model of a typical large aperture optical component to get the deformation of the optical component. The results indicate that the deformation of the optical component can satisfy the stability requirement in the current environment. Meanwhile, the deformation of the optical component is calculated for different temperature changes and the results show that the deformation of the optical component have a direct relationship with the change of temperature.
