Embodiment Construction
[0053] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0054] Such as figure 1 As shown, the embodiment of the present invention provides a single-point progressive molding control method for spherical wall panels with lattice ribs, including:
[0055] Step 101': Obtain an initial forming path and a target deformation amount, the initial forming path includes a first initial path and a second initial path;
[0056] Specifically, both the initial forming path and the target deformation are preset values. According to the theoretical three-dimensional model of the spherical integral wall panel, the effective layout of the structural outline, grid ribs and flange positions of the spherical integral panel can be analyzed to determine the initial forming path and target deformations;
[0057] Step 102': According to the initial forming path and the target deformation amount, determine the first form...

Abstract
The invention provides a single-point progressive molding control method, device and system for a spherical wall plate with grid ribs. By dividing the forming path into the first forming path and the second forming path, the corresponding deformation amount is determined according to different forming paths, and each forming path and the corresponding deformation amount are simulated and verified, and the model suitable for the spherical wall of grid ribs is obtained. The first forming path and the second forming path of the plate, by changing the forming path and the corresponding deformation amount, can adapt to the inability to single-point progressive molding in the grid rib spherical wall panel structure due to the uneven distribution of the spherical structure and grid rib stiffness. Forming problems.
Description
technical field [0001] The invention belongs to the technical field of forming technology for a bearing structure of a space vehicle, and relates to a single-point progressive molding control method, device and system for a grid rib spherical wall plate. Background technique [0002] The aluminum alloy flange mesh rib spherical integral wall panel belongs to the large-scale lightweight integral wall panel structure in the aerospace field, and has obvious weight reduction effect, which can reduce the structural weight by 10% to 30%. The aluminum alloy flanged grid rib spherical integral wall plate is the core structure for establishing a manned long-life space station. This structure is an upgrade and surpass of the large thin-walled spherical skin-sealed structure widely used in space stations at present. Compared with the large thin-walled spherical skin sealing structure, the aluminum alloy flanged grid rib spherical integral wall plate not only greatly improves the streng...
