[摘要] 根據(jù)虛功原理，先離散后用歐拉-馬克勞林求和公式推導(dǎo)出空心板橫筒方向等效厚度的數(shù)值解法。并對(duì)該解法的計(jì)算結(jié)果采用有限元數(shù)值模擬對(duì)比分析，對(duì)比表明本文給出的數(shù)值解法對(duì)于跨度稍大時(shí)，計(jì)算結(jié)果精度比較理想，可以用于設(shè)計(jì)參考。

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.
