The influence of steel band gap between the layers

Packaging steel strip manufacturer to introduce the influence of the clearance of the steel strip layer under before handling of clearance between multiple container layer, besides the shutters model, and the following two ways: 1) Ideal joint module left between the layers. Such as thermal shell pressure container, think through precision machining can make the appearance of the single cylinder size to meet the requirements of the amount of interference, laminating interlayer can be ideal, stress calculation when ignoring the influence of the clearance between the layers. 2) Elastic layer between concepts. Using shell through the play between the interaction of multiple concentric cylindrical shell to simulate the multi-layer container, with circular and radial elastic properties of different orthogonal cylindrical shell instead of a multi-layer container, and the measured data is used to determine relevant parameters. Obviously, the model and the interlayer is ideal joint model has bigger difference with the actual situation of multi-layer containers, are the two kinds of multi-layer container extremes; Fetching can involve the reflection of the concept of elastic layer between the actual situation of multi-layer containers, friction effect between qiao did not consider the model layer, fault should not be used for processing steel strip steel band wound pressure vessel under the influence of the clearance of the layer.
