FEMES是用于支撑航空结构有限元建模和分析的智能化软件。在视窗(WINDOWS)支持下采用C~(++)/C语言,按面向对象的设计方法编程。它考虑了结构中带受力或部分受力口盖的开口、加强筋、偏心等结构异型以及弹塑性、稳定性等非线性效应影响,通过迭代自适应地修改模型;能定量化地输出NASTRAN程序使用的模型数据,并可通过解释推理过程对分析人员进行建模知识的培训。FEMES系统在××机的机翼和中机身有限元模型中进行了建模和修模的测试应用,结果表明,FEMES的应用提高了实际结构计算结果与试验结果的相符程度。
FEMES is an intelligent software for supporting the finite element modeling and analysis of aeronautical structures. In Windows (WINDOWS) support using C ~ (++) / C language, object-oriented design method programming. It takes into account the non-linear effects of structure-type openings, ribs, stiffeners, eccentricity and other non-linear effects such as elastic force or partial force in the structure, elasto-plasticity and stability, and adaptively modifies the model through iteration. The program uses model data and can train analysts in modeling knowledge by interpreting inference processes. The FEMES system was used to test the model building and repairing in the finite element model of wing and mid fuselage of the ×× machine. The results show that the application of FEMES improves the consistency between the actual structural calculation and the test results.
