The Optimizing Design of Combined Pressure Vessel

In accordance with the internal pressure calculation formular derived from the Reference Material 1 for fiber-reinforced pressure vessel, this paper sets up the mathematical model for optimizing design and achieves the optimum solution by using compound method. The analysed results show that the material cost of combined pressure vessel is lower than the pure steel vessel and that the weight of combined pressure vessel is much decreased in the same condition of internal pressure and containing volume.
