The tank panel is the main load-bearing component of the rocket body.It is difficult to avoid unexpected deformation in the manufacturing process,and the panel must be corrected in the later stage.In order to solve the problems such as unstable quality,loud noise and high labor intensity in the manual hammering of the tank panel,this paper takes the aluminum alloy high-reinforced panel of the typical aerospace cross-reinforced structure as the research object,and introduces a mechanized method to calibrate the panel.Firstly,the mechanical calibration device and the calibration scheme are designed,and then the finite element software ABAQUS is used to simulate and analyze the variation law of the calibration force required for the deformation correction of the wall panels with different errors,and the functional relation between the calibration force and the calibration quantity was fitted out.On this basis,the calibration is good,the contour accuracy is high,and it meets the requirements of manufacturing.The research shows that the mechanical calibration scheme is effective for the calibration work of aluminum alloy tank panels,which is helpful to meet the requirements of high quality and high efficiency manufacturing brought by the increase of types of panels in the future.
