Embodiment 1

[0045] In this embodiment, the invention provides a method for impact forming of an aircraft wing, the flow chart of which is as follows figure 1 shown, including the following steps:

[0046]Step 1: Calibrate the aircraft wing to obtain the layered impact parameters of laser peening. First, the big data software reads the 3D model data of the aircraft wing parts and the blank, and interpolates the machining allowance between the aircraft wing parts and the blank according to the elastic-plastic properties of the material to obtain the laser shot peening layered data; Secondly, the big data analysis system plans a variety of laser peening trajectories and processing parameters on each layer, and generates simulation files that can be recognized by finite element analysis software, such as the INP file format that can be recognized by Abaqus software. Call the finite element simulation software to calculate and analyze the simulation file; read the calculation results of the f...

Abstract

The invention relates to a method and device for laser shot-blasting forming of an aircraft wing. The device for laser shot-blasting forming of the aircraft wing is composed of a two-axis rotating workbench, a laser device, a lens assembly, a control device, a big data analysis system and the like. The control device plans position information of laser shock according to information of the big data analysis system and controls the two-axis rotating workbench to rotate according to the position information, so that the wing is rotated to the shock position, and the lens assembly is controlled to move to the shock position at the same time. The lens assembly measures the distance between the shock position and a lens and moves the focusing lens to focus lasers to the shock position, and the required spot diameter is obtained. After the lens assembly is positioned, a signal is emitted to a control system, the control system controls the laser device to emit lasers according to planned laser shock parameters, shock waves generated by the lasers are used for making a workpiece deform, and thus forming is achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, in particular to an aircraft wing impact forming method and a control device. Background technique [0002] Laser shot peening is to irradiate the surface of the material with short-pulse high-power laser, the material is vaporized and a high-pressure shock wave is generated on the surface of the plate. When the shock wave intensity is greater than the dynamic yield strength of the material, the plate will undergo plastic deformation, thereby causing the plate to Bi-directional bending deformation that is convex toward the sprayed surface. Laser shot peening has the advantages of no mold, simple process equipment, large processing flexibility, precise control of the laser pulse parameters can accurately control the shape of the shot peening, the forming curvature is larger than that of mechanical shot peening, and the compressive stress on the surface of the part can improve the fa...
