Abstract

Based on iSIGHT optimization platform and ABAQUS, the frames of rocket liquid engine with multiple forms are optimized. Fast parametric modeling method, sensitivity analysis method and multi-objective genetic algorithm NCGA are combined to optimize the dimensions of frames. The frame modeling of different forms can be accomplished by using specified frame design parameters, thus greatly improving design efficiency. Finite element analysis and optimization were carried out on a single four-point pusher frame as an example. The influence of different section size parameters on the frame performance is analyzed. The optimized structure of frame reduces the amount of material used and increases the first order natural frequency within the constraints.
