Abstract

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