LMS Samcef package 复合材料

复合材料将其他材料的优势集中在一起,能够具有高强度,刚度及较轻的重量;不易腐蚀;热和电绝缘;复合材料可以被塑造为复杂形状。复合材料的应用面临的挑战:增加效率及可靠性;复杂的造型及设计灵活性;减轻重量以降低功率损耗。软件仿真目的是需要研究复合结构的整体特性及部件特性,以对部件进行减轻质量,提高经济性的优化。
LMS Samtech, 拥有在复合材料的30年的经验,主要服务于ASD行业,但同时也在其他领域崭露头角,如汽车底盘,风机桨叶等等。复合材料建模,主要针对长纤维机构,如层压板,纤维缠绕结构,夹层平板等。建模时,需要利用完整的有限元库: 3D multi layer element(壳单元),3D element volume(1 ply by element);3D shell + volume。然后用求解器可以通过热分析求解从线性到非线性问题;复合材料的求解分析集成在CAESAM环境中。CAESAM介绍:CAESAM is a high level CAE centric application framework. It allows the customization and management of the customer’s whole engineering process, potentially involving any commercial software and in-house skill tools. This environment is based on knowledge based engineering concept: it encapsulates customer skills and knowledge into analysis processes and analysis methods. This ensures reusability, which leads to reduction of costs and time to market. CAESAM can be linked to the customer PDM and data can be shared within and across CAE analysis disciplines. It is used by several companies like airbus in Europe or avic in Asia.在Samcef软件包中对复合材料的建模,不需要额外软件的辅助。LMS Samtech 可以利用一些接口进行协同仿真,实现热-机械分析的数据交换。附件为samcef 复合材料简要介绍
