| Abstract | A method for generating mass cruciforms for use in finite element structural models is introduced. A review of the mathematics necessary to create mass cruciforms is given. A discussion of the potential applicability of mass cruciforms is given which emphasizes its use to model propulsion systems. This is demonstrated by the use of mass cruciforms on the Boeing High Speed Civil Transport finite element model. The decision to use mass cruciforms to represent inertial properties of a structural component is influenced by several factors. These include availability of mass and inertia data during the initial preliminary design stage. Additionally, they include desired finite element model discretization and software requirements and limitations. These topics as well as those relating to dynamic loads and flutter analyses will be discussed. |
