Abstract

The invention provides a tailor-welding device and tailor-welding method for an inner-layer connecting ring of a low-temperature wind tunnel. An elliptical frame mold is of an elliptical-ring-shaped twenty-four-sided structure and is used for being connected to the outer circumferential wall of the elliptical-ring-shaped inner-layer connecting ring in a sleeving mode; an elliptical frame is of an elliptical-ring-shaped structure and is arranged at the central position in an inner cavity of the elliptical frame mold, the central point of the elliptical frame coincides with the central point of the elliptical frame mold, the long axis of the elliptical frame coincides with the long axis of the elliptical frame mold, and the short axis of the elliptical frame coincides with the short axis of the elliptical frame mold; one end of a rigid supporting assembly is welded to the outer circumferential wall of the elliptical frame, and the other end of the rigid supporting assembly abuts against two sides of each weld joint on the inner-layer connecting ring; and a fastening assembly is installed in the middle of each set of edges in the elliptical frame mold and used for fastening the inner-layer connecting ring. With the device and the method, the assembly precision of the inner-layer connecting ring is effectively improved, and the deformation in the welding process is controlled.

Description

technical field [0001] The present application relates to the field of wind tunnels, and in particular to a tailor welding device for an inner connecting ring in a low temperature wind tunnel and a tailor welding method for an inner connecting ring. Background technique [0002] Since the advent of the wind tunnel, the application of wind tunnel technology in aerodynamic research and aircraft development has made significant progress, and its role has become increasingly significant. However, as the test objects (such as aircraft) become larger and larger, conventional wind tunnel tests face some serious challenges, the most important of which is that conventional wind tunnels cannot conduct tests within the full-scale Reynolds number, and high Reynolds number wind tunnel tests are the key to realizing aircraft The premise and guarantee of fine aerodynamic design and accurate prediction of flight performance, the cryogenic wind tunnel was born and developed to solve this pro...
