摘要
智能材料的发展给结构设计带来新的方向,同时也给商用有限元软件的应用迎来新的挑战.由于MSC Nastran的局限性,尚不能很好地模拟一些智能材料.结合实际工程需要,利用Patran完善的前、后处理功能及二次开发语言,将一维形状记忆合金(Shape Memory Alloys,SMA)材料系统集成到Patran中,能方便地实现在Patran中定义其材料属性和对布置有SMA的驱动结构以及复合材料结构的快速建模分析,最后利用本文系统建立SMA复合梁以及SMA丝驱动的机翼后缘模型,并进行验证,证明此模块功能的正确性和有效性.
The development of smart materials brings a new way for structural design as well as a new challenge to commercial finite element software. Due to the limitation of MSC Nastran, it is impossible to simulate smart materials. Combining with practical engineering, the 1D shape memory alloy system is created and integrated in Patran based on its perfect function of pre-processing, post-processing and its secondary development. It is easy to define the properties of shape memory alloys. The direct modeling and analysis on the composite materials and the shape memory alloys system are done. The composite beam and wing rear actuator embedded with SMA wires are built to verify its functional correctness and validity.
