Description

Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing, in particular to a multi-point loading deviation compensation device for a large reinforced wall panel. Background Art

[0002] Reinforced structures are widely used in aerospace due to their lightweight and high load-bearing capacity. They are a key component of rocket tanks. During the rocket tank manufacturing process, sheet metal is milled and rolled to form the reinforced structural components with a defined curvature. These components are then welded to form cylindrical sections, which are then girth-welded to form the complete tank. During this manufacturing process, residual stresses generated during the machining of the reinforced structural components can cause warping after rolling, resulting in misaligned butt joints in the girth welds of the welded sections, making smooth welding impossible. Therefore, the manufacturing accuracy of the reinforced components significantly impacts the deviation and accuracy of the overall structure. Due to the presence of stiffening ribs, deviation compensation for reinforced structures cannot be achieved using a single die for stamping and loading; instead, multiple localized loading methods can be employed. Traditional compensation methods use a reverse displacement method to determine the loading position point by point, resulting in low accuracy and reliance on manual experience, leading to inefficient compensation. Therefore, it is necessary to understand the deviation compensation characteristics of large reinforced panel structures under multiple localized loading conditions to improve the reliability and efficiency of multi-point localized loading compensation for large reinforced structures.

[0003] Current multi-point loading compensation systems for large reinforced structures face the following challenges: The high degree of freedom in the placement of the loading points leads to a high degree of randomness in their layout, necessitating a high degree of freedom in the experimental equipment. Furthermore, the loading stroke of each loading point in multi-point loading compensation requires independent control. Existing multi-point forming equipment is primarily used for loading compensation of panels and is poorly suited for use with reinforced structures. Therefore, a multi-point loading deviation compensation device for large reinforced wall panels with a high degree of freedom and the ability to precisely adjust the loading points and loading stroke is needed.
