Abstract: aking example for T21 Aluminumtriethide tank, introducing the whole finite analysis process of  portable tank, a finite model for thin shell element and solid element was established, and has been taken into account. The optimal structure designing of vessel supports was accomplished, the analysis results indicated the portable tank by the motion direction of the inertial force and saddle structure before and after optimization should force changes in the larger, saddle before optimization of the maximum stress was 38.89 MPa, saddle after optimization of the maximum stress was 130.58 MPa.

Key words: Portable tank, Shell element, Solid element, Aluminumtriethide, Finite element analysis

摘要： 以T21型三乙基铝储罐为例,介绍了可移动罐柜的整体有限元分析过程。分别以壳单元与实体单元
为对象建立有限元分析模型,进行了有限元分析计算,并对支座的结构进行了优化设计。通过分析得知,可移动罐
柜受运动方向的惯性力时,鞍座结构优化前后应力变化较大,优化前的鞍座最大应力为38.89MPa,优化后的鞍座最
大应力为130.58MPa
