Abstract: Based on the principle of virtual work, a first discrete, after using Euler - Madaurin sum formula of the sum that is the hollow cylinder transverse direction equivalent thickness of the numerical solution. And on the method of calculating results using the finite element numerical simulation analysis. Contrast this paper shows that the numerical solution for the larger span, the results more satisfactory accuracy, can be used for design.
