Abstract

Based on the technical requirement of a certain distortion correction system for infrared imaging system, we design the structure of distortion board and establish the three-dimensional model by Pro/Engineer. Then, modal analysis is done by Pro/MECHANICA. The natural frequency and the first four vibration models of the distortion board are obtained. The analysis results show the weak link of the structure and reliable foundations are provided for the optimization design of the structure. The article proposes the net distributed reinforcing rib. The modal analysis results show that the presented optimization design has comparatively high natural frequency and meet flatness requirement, so it will produce a better measurement performance.
