通用截面特性计算软件开发研究
Research on the Development of Common Calculation Software for Section Property
摘要
Abstract
In order to find a section property calculation method for arbitrary cross sections and develop the common efficient software,the mathematical expressions of area,static moment,moment of inertia and product of inertia are studies deeply.The area double integral boundary curve integral in the section property mathematical expressions is transformed to boundary curve integral with Green formula.The boundary curve integral from tow parameter is converted to one parameter by curve parameter equation.The section properties are calculated by Newton Leibniz formula,and then,the common section property calculation software is developed by means of object-oriented method.The software is proved to be flexible and convenient,and suitable for arbitrary composite sections.The application in a large number of engineering design projects shows that the method is accurate and efficient with prominent practical significance.关键词
