Abstract

Compared with the traditional single-channel multi-spectral remote sensing camera, the multi-spectral remote sensing camera with dual-channel imaging can capture more spectral information of spectral segments. In order to make the dual-channel multi-spectral remote sensing camera image well in various complex mechanical environments, the structural dynamic analysis of the camera was carried out. First, the optical system and structural composition of the two-channel camera are introduced. After that, using the Patran finite element analysis software, based on the establishment of the finite element model, the modal analysis, overload adaptability analysis and random vibration analysis of the camera were carried out. According to the analysis results, a damping isolator is added to each mounting foot of the camera, which effectively reduces the random vibration response of the camera's key measuring points. Finally, the mechanical environment test of the camera is carried out. The results of finite element analysis and test are in good agreement, which verifies the correctness of the analysis and calculation results. It shows that the dynamic performance of the dual-channel multi-spectral remote sensing camera with the outer envelope size of 1500×1500×1000mm meets the design requirements.
