Quick modeling system for large structure

Abstract

The invention discloses a quick modeling system for a large structure. The quick modeling system comprises a foundation database module, a structure overall modeling module, a structure quick output module and a main structure modeling module, wherein the structure overall modeling module is used for performing structure overall modeling according to parameter requirements of skeleton template overall opening and interface and the like and can be used for a wireframe model for strength finite element analysis; the main structure modeling module is used for performing main structure parameter design according to the initially optimized structure parameters and completing main structure three-dimensional digital prototype modeling on the basis of a skeleton of the structure overall modeling; the structure quick output module is used for detailing the model according to requirements such as strength finite element analysis and three-dimensional labels to complete quick modeling of the large structure; the foundation database module provides information support for modeling.

Description

technical field [0001] The invention relates to the technical field of structural modeling, in particular to a rapid modeling system applied to large structures. [0002] Background technique [0003] In the existing technology of structural modeling in the aerospace field, the common method is to design each component first, and then carry out the overall assembly coordination after completing the design of the components. The advantage of this modeling method is that each model is independent, the requirements for machine configuration are low, and the requirements for personnel design ability are low. The disadvantage is that the design process lacks an overall concept, the modeling is not standardized, and the modification workload is heavy when external conditions change. The application of this design method has certain limitations in the aerospace field that requires strict design standardization, refinement, and rapidity. [0004] In the structural system of the la...

Problems solved by technology

[0004] In the structural system of the launch vehicle, there are nearly 20 compartments with independent functions and requirements. If the traditional modeling design method is used, the modeling cycle is long and the modification is difficult. Moreover, the modeling of each compartment is not standardized, and the structural matching is poor, which seriously affects work efficiency
