[0056] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0057] A method for predicting warping deformation of a thin-walled component space envelope forming according to the present invention comprises the following steps:
[0058] S1. Determine the principle of space envelope forming of thin-walled components. The initial state of space envelope forming of thin-walled members is as follows: figure 1 as shown, figure 1Among them, 1 is the enveloping mold, 2 is the blank, and 3 is the lower mold. The envelope mold rotates around its own axis and the central axis of the thin-walled member at a speed of n=4rad / s, and the lower mold drives the blank placed in the lower mold to approach the envelope mold at a feed speed of v=2mm / s. With the increase of the feed rate of the low...
