摘要
把有限元法应用到风洞天平结构设计,对其整体结构进行了计算,得出了风洞天平各种载荷作用下的应力场。根据计算结果,可以准确地发现危险截面的应力集中程度和弹性元件所在截面的最大应力部位,最终为确定各个载荷分量之间的相互干扰及弹性元件的测试点提供可靠的依据。
The application of Finite Element Analysis FEA to the design of the structure of wind tunnel balance obtains the rule of stress distribution on the wind tunnel balance by computing the whole body. Based on the result of computation , the degree of stress focusing on the dangerous section and the maximum stress position of the section , where lies the elastic element, are found precisely. Both of them provide basis ultimately for determining interference among other loads and the measurement point of elastic element .The paper mainly studies the axial force element.
