摘要

The starting and the stopping of the moving carrier can cause tens of thousands of gravitational accelerations ofmechanical impact, which may lead to the damage of photoelectric detection parts, especially the optical system. For thestudy of the anti-overload ability of the optical system in strong impact environment, based on the finite elementmodeling method, taking the optical system with a diameter of 35 mm lens as the subject, the deformations and the stressnephograms of different materials of optical lenses under 10000g impact condition are obtained and the influences ofdifferent lens mounting structures on anti-overload ability of the system is analyzed. The consistency of the simulationresults and the physical model test results, fully illustrates the correctness of the theory and the model. This paperexplores an effective way for the analysis of the mechanical and structural evolution characteristics of optical system instrong impact environment.
