摘要
在飞机结构设计中,已经广泛采用有限元作为设计工具。在飞机结构布局设计阶段,快速的建立满足分析精度要求的全机有限元模型,能大大提高结构设计的质量和效率。但从结构数模到有限元网格的划分要经历复杂的过程,提高和简化有限元分析的前处理非常必要。主要研究了在飞机结构布局设计阶段全机结构有限元建模的关键技术,并结合LMS Virtual.Lab Structures举例说明。根据探讨的有限元建模关键技术,可以建立符合飞机结构初步分析阶段精度要求的有限元模型。
The FEA is widely used in aircraft structure design. In the preliminary design of structural layout, making the reasonable finite element analysis model of the whole aircraft structure can improve the quality and efficiency of design. Because the process from the structure model to the finite element mesh model is very complicated, improving and simplify the finite element analysis is very necessary. This paper mainly works at the key technology of FEA model of the whole structure of aircraft in primary design of aircraft with the examples of LMS Virtual.Lab Structures, such as modeling of structure, model data transfer, meshing, accuracy can be made based on the key technologies load and boundary conditions. this article discusses. The model meet the requirements of
