Abstract: In order to study the anti-high-overload mechanism of projectile-borne optoelectronic devices, a numerical simulation model of projectile-borne opto- electronic devices is established according to the artillery launching environmental characteristics. A theoretical analysis model of projectile-borne optoelectronic devices is also established to solve the stress, strain and relative velocity of projectile-borne opto-electronic devices. The result shows that the numerically calculated results are in good agreement with the simulated results to verify the correctness of the theoretical analysis model. The proposed model can be used for the reseasch on the dynamic characteristics of the projectile-borne devicess and the theoretical analysis of anti-high-overload design.
