STRUCTURAL DESIGN IN FILAMENT WOUND SPHERICAL PRESSURE VESSEL WITH POLAR OPENINGS OF

摘要

The structural form, load-bearing state and design method for layer lay-up of FW spherical pressure vessel with polar openings of different sizes were introduced. The function concept of the relationship between conversion coefficients of fiber strength with fiber position in the spheroid was suggested. By changing the conversion coefficient of fiber strength at special points, optimal structural design for spherical vessel was conveniently conducted.
