摘要:
应用刚度等效原理导出肋型板的等代无肋板厚度计算显式,方法既适用于不同纵、横梁布置的板,也适用于板边各种支承情况,包括边界点支承的板.针对工程中肋型板不同的边界约束状况,给出挠曲试函数各种形式.计算过程涉及的数值积分简便易行,便于工程技术人员运用,与有限单元法相比,无需计算机程序.多个典型算例的结果表明,代换前后板上的挠度分布特征及扭转角分布特征与有限元法计算结果在3%~6% 误差范围一致.
Abstract:
The method to derive the thickness calculation expression of rib board by the principle of equivalent stiffness of the rib board is applicable to not only the board arranged in transom and longitudinal beam, but also all kinds of support conditions at plate edges, including the supported plate on boundary points. In allusion to different types of boundary constraints status of rib board in engineering, various forms of buckling trial function are given. With only simple numerical integration involved in the calculation process, it is convenient for the application of engineering and technical personnel. Compared with finite element method, the computer program is not needed. The results of several typical examples show that the deflection distribution and reverse angle characteristics of the front and back plate are consistent with the calculation result of finite element method with the calculating error of 3%~6%
