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
