According to the design criteria of mechanical joints and differential pressure load, a study is performed on panel splices design of a double bubble intersection in a composite pressure cabin structure. Two different panel splices of the double bubble intersection in a composite fuselage are designed under differential pressure loads, and the transverse displacement of the panels is analyzed by a shell-beam finite element model. Then the strength of butt joint concept is checked. The load distribution of the multiple-bolted joints in the structure is first calculated by using fastener elements; then the failure strength of the panel splices is assessed by failure analysis on single-bolted joints at critical locations. The result demonstrates that the butt joint design concept can improve the transverse displacement of the panels significantly under differential pressure loads and satisfy the design requirements.
