ANALYSIS OF LOAD TRANSMISSION LINE ON THE FUSELAGE OF REUSABLE LAUNCH VEHICLE

摘要

In order to optimize the fuselage structure of reusable launch vehicle, the load transmission line wasanalyzed by FEM methods. The FEM model included propellant tank, fuselage and the joint between them. The loadtransmission analysis was undertaken in two load cases, including maximum axial acceleration and the maximumtransverse acceleration. The results showed that the different joint structure induced different percentage of load thattransferred to the fuselage and the propellant tank. Suggestions were proposed for designing the connected structureaccording to the result of the analysis.
