    In order to strictly keep the development schedule of a next-generation aircraft, an improvement of structural analysis accuracy to prevent nonconformance of the airframe structure in the design stage has been demanded. To meet such demands, structure analysis using a large-scale FEM model is needed. On the other hand, considerable labor cost and time are required to establish a large-scale FEM model. Therefore, technology for automatically creating a FEM model is essential. Mitsubishi Heavy Industries, Ltd. (MHI) has developed an automated structure analysis tool based on a general-purpose analysis tool through in-house research conducted by MHI and the R&D project "Research on lightweight airframe structure" which were conducted by the Acquisition, Technology & Logistics Agency. This report describes the automated tool assuming the design method based on FEM-based structural analysis. We realized the possibility of achieving a higher efficiency (reduction of man-hours by 50% or more) by using this automated tool compared to the conventional method.
