In this report, a new design technique for the fire prevention tank made
of steel is proposed for improving a high pressure resistance of the tank
and shortening the lead-time in the production.
A simple calculation method based on JIS has been used for the conventional
design. However the precise strength evaluation cannot be obtained for
the pressure over an automobile weight by this method. We developed the
design technique that is applicable to the high pressure of an airplane
weight by using both 3D-CAD and FEM analysis. The reliability of the strength
evaluation for a horizontal type cylindrical tank was improved by this
method. As a result, the tank with the pressure resistance of 3000kN was
designed.
