In order to improve the structural design efficiency, design quality and iterative efficiency of the spacecraft casting cabin in the scheme demonstration stage, the structural parameters of the casting cabin are studied in combination with structural characteristics of the spacecraft with complex surface, and the curve curvature method is used to express the parametric layout of longitudinal reinforcement. The publication elements of the cabin structural frame model are defined to achieve the Top-Down design of the casting cabin. Simultaneously, a rapid parametric design method for spacecraft casting cabin structure is proposed, normalized modeling is implemented by defining casting feature naming rules and creating feature sets, the rapid design is realized by encapsulating cabin design knowledge, and the feature parameterization is realized by creating feature parameters and formulas. Finally, the rapid design environment for the interactive casting cabin structure is established, rapid structure design and rapid structure modification of casting cabin structure are realized, and the feasibility and effectiveness of the proposed method are verified by the example of spacecraft casting cabin.
