| 摘 要： | 作为一种新型的复合材料,三明治板结构在轻量化轨道车辆设计中具有广阔的前景,然而由于这种结构的复杂性也给结构的有限元分析带来了一定难度。文章研究了3种不同三明治板结构二维简化有限元分析方法,并与三维实体单元模型分析进行比较,由此得到一种较为简便、适于微机计算规模且满足工程分析精度要求的有效建模方法。

| Abstract: | As a new kind of composites, sandwich panel structure has great promising future in railway vehicle lightweight design. However, its complexity brings difficulties to finite element analysis. This paper develops three different simplified 2D FEA modeling methods, which are compared with 3D substantiality model analyzation. A modeling method is obtained which is easy in modeling, and with the precision to satisfy the engineering requirements. |
