Taking an upper-stage liquid rocket engine thrust frame as an example, this paper studies structural optimized design methods by finite elements analysis software ANSYS. Setting up the parametric modeling, obtained the best result by zero order and first order methods. Furthermore, this paper validated structural strength and stability. The mass of thrust frame was lightened consumedly via optimum, and the effect of optimum was obvious.
