The bearing structure of the general cylindrical shell consists of a plurality of cabin sections, and the connection between each part is as follows: gluing; secondly, bolt connection is carried out; novel connections (including but not limited to hybrid connections, Z-Pin connections, electromagnetic riveting, stitch connections, etc.). The cementing is not similar to the bolting and needs the opening, which easily causes the stress concentration at the opening and reduces the structure performance. The glue joint has the remarkable advantages of high connection efficiency, light weight, fatigue resistance, corrosion resistance, better shock absorption, sealing performance, insulating performance and the like, and is often used as a connection mode between a cylindrical shell and an assembly flange. But the adhesive bonding also has the disadvantages: and a reliable and stable detection method is lacked, the bonding quality is difficult to control, and the reliability is poor. In actual assembly, the accurate alignment of the thickness of the glue layer and each part is difficult to achieve. And the simulation calculation finds that: the slight change of the thickness of the adhesive layer may cause the stress of the adhesive layer to fluctuate greatly, resulting in the premature failure of the adhesive layer. In short, the realization of controllable glue layer thickness is the key to ensure the forming quality of the cylindrical shell structure. However, most of the existing cylindrical shell assembling and bonding technologies are manual assembling, and the revolving body is difficult to fix, so that the operation is complicated, time-consuming and labor-consuming, the bonding quality is difficult to fully guarantee, and the risk in the subsequent use process is greatly increased.
