Abstract:
A rapid optimization design method was established for the frame structure of a rocket engine with double thrust chambers, including parametric modeling and structure optimization design. The rationality to conduct optimization design by means of a simplified model with beam and MPC elements was validated by comparing the structure analysis results of two different frame entities and a simplified model. A finite element model file including the frame structure layout and size information was generated directly by self-compiled program, which improved the modeling precision and decreased the modeling time. The strength, stiffness and stability of the frame structure were considered in the optimization design of the frame structure layout and light weight. The frame weight was decreased significantly under the condition that all restrictions were satisfied. A ideal effect of
