Research on theoretical calculation method of hyperbolic rotating thin shell bending problem

Objectives In order to analyze the bending characteristics of hyperbolic rotating thin shell, Methods the complex two-dimensional mechanical problem of hyperbolic rotating thin shell is simplified to a one-dimensional bending problem based on Euler’s Bernoulli beam theory. By analyzing the force and deformation characteristic of shell and belt beams, a structural mechanical model was established, and a double curvature rotating thin shell bending differential equation was established by combing the physical equation of plate and shell theory and the bending differential equation of single-span beam. An empirical formula for typical stress is proposed, and the accuracy of the formula is verified by the simulation based on ANSYS. ResultsThe error between the simulation and the formula is about 5%, Conclusionswhich shows that the formula has high accuracy in predicting typical stress, and which verifies the correctness of the theoretical calculation method. This method can provide reference for the design and optimization of similar structures.
