Abstract

The invention relates to the big data field and discloses a modeling method for rapidly generating a flight load analysis model. The method includes the following steps of 1 arranging cutting surfacesin two directions of each component by taking each component of an aircraft as a unit, and forming a discrete small curved surface after the cutting cycle operation; 2 performing the same operation on each discrete small surface by using the MATLAB program: obtaining the normals of the discrete small surfaces, and obtaining the geometrical and physical attributes of the discrete small surfaces ofthe face center, the normal vector and the small block area according to the normals; 3, taking all that components of the aircraft as units, discretely cutting all the components of the aircraft, obtaining the face center, the normal vector and the small block area attributes of all the components, and reasonably ordering and establishing a flight load analysis model. The technical proposal of the invention establishes the discrete model with reasonable and moderate mesh quantity, remarkably improves the modeling speed of the flight load analysis model through the cycle of the program, and lays a good foundation for the subsequent flight load analysis and design work.

Description

technical field [0001] The invention relates to the field of big data, in particular to a modeling method for rapidly generating a flight load analysis model. Background technique [0002] Flight load analysis is a very important link in the aircraft design process. It undertakes general, aerodynamic, performance, flight control and other majors to provide design basis for structural and strength design analysis. Quickly and accurately obtain the flight load data of the whole aircraft and components to lay the foundation for aircraft design. [0003] The modeling of the flight load analysis model is an important task in the pre-processing of the flight load analysis. The shape of the aircraft is a complete whole. Geometric and physical properties of discrete small surfaces on aircraft surfaces: face center, normal vector, and patch area. The traditional flight load analysis model modeling method has defects such as slow speed, inaccurate geometric and physical properties, ...
