| Abstract: | Let the impact loads be transformed into simulated dynamic loads by the use of dynamic load coefficient, taking this as a foundation the structural optimization mathematical model of ejection seat was established by applying the variable density method. The structural optimization designing method of ejection seat under impact loads was put forward. And the living example; calculation of structural optimization design was carried out, thus the optimized structure that could satisfy the action of impact forces was obtained. |
