Abstract: A determination device may include an acquisition unit configured to acquire first degradation values that indicate respective degradation degrees of a plurality of components of a same type, and regard the respective first degradation values of the plurality of components as respective first usage values of a plurality of usage environments in which the plurality of components are used. The determination device may include a determination unit configured to determine, based on a target value that indicates a predetermined target degradation degree of the plurality of components, a first combination of the respective first degradation values of the plurality of components and the respective first usage values of the plurality of usage environments.

Abstract: A flying object includes a housing formed by combining a plurality of panels having reinforced fibers and a matrix resin, and a low melting point member having a lower melting point than that of at least the reinforced fiber, wherein the housing is configured to be breakable according to a change of the low melting point member during either of fusion or sublimation.

Abstract: An automobile vehicle body and an automobile vehicle body manufacturing method is provided in which a metal joint is divided into an upper joint and a lower joint. The upper joint includes an upper wall which is fitted into a side member, a vehicle width direction inner wall and a vehicle width direction outer wall, and a lower joint includes a lower wall which is joined to a lower face and an outside face of a vehicle body floor, and the vehicle width direction outer wall, and therefore, the vehicle width direction outer wall of the upper joint is fastened to the vehicle width direction outer wall of the lower joint by a first bolt, and the vehicle width direction inner wall of the upper joint is fastened to an inside face of the side member by a second bolt.

Abstract: An automobile body and a method for manufacturing the same is provided in which a substantially rectangular windshield joining face is formed by a front roof arch, a front portion of roof side rails and a dash panel upper of a lower skeleton. Since the upper skeleton and the lower skeleton can be separated, there is the problem that a gap occurs between lower ends of the roof side rails of the upper skeleton and the vehicle width direction outer ends of the dash panel upper of the lower skeleton, and the windshield joining face is discontinuous. Extension parts are provided inward in the vehicle width direction from the lower ends of the roof side rails, and the vehicle width direction inner ends of the extension parts are connected to the vehicle width direction outer ends of the dash panel upper, thereby eliminating discontinuity of the windshield joining face.

Abstract: In a body structure of an automobile, a floor panel having a sandwich structure in which a core is sandwiched between and joined to an outer skin and an inner skin, which are made of a CFRP, and a first load-dispersing frame extending in the fore-and-aft direction along a side sill is disposed between an energy-absorbing member and the core. A locally concentrated load inputted into the side sill is absorbed by crumpling of the energy-absorbing member of the interior of the floor panel beneath the side sill and then widely dispersed through the floor panel further inside in the vehicle width direction than the side sill by the first load-dispersing frame, and local destruction of the floor panel further inside in the vehicle width direction than the side sill is inhibited. Furthermore, by increasing bending stiffness of the first load-dispersing frame, to reduce the sheet thickness of the CFRP outer and the inner skins, a light weight is achieved.

Abstract: An automobile body structure is provided in which a carbon fiber-reinforced plastic cabin formed of a bathtub shape includes an inverted U-shaped roll bar providing a connection between front parts of a pair of left and right side frames, and a pair of left and right roll bar-supporting bars connecting an upper portion of the roll bar to rear parts of the pair of left and right side frames. Since a rear part of a roof panel and a front part of a tailgate panel are supported on a mounting bracket provided on the roll bar-supporting bar, it is possible, by changing the fore-and-aft position of the mounting bracket, to freely set the rear end position of the roof panel and the front end position of the tailgate panel and, moreover, it is possible to strongly support the roof panel and the tailgate panel.
