A product design CAD data reconstruction unitreconstructs product design CAD data used for product evaluation regarding an initial design so as to fulfill restrictive conditions obtained from the product evaluation based on a product structure for the initial design. The reconstructed product design CAD data is stored in a product design CAD data database. Upon reception of a corrected design obtained by correcting the initial design, the product design CAD data for the initial design is read from the product design CAAD data database, and the product design CAD data is corrected along a design surface of the corrected design.

Power train arrangement structure for vehicles

A body structure for an electric vehicle, which has a battery carrier for containing a battery disposed on a vehicle body thereof, the body structure comprising: a supporting mechanism, which supports the battery carrier; a movement-restricting member, which restricts movement of the battery carrier; and, an energy transfer-control member, which controls transfer of kinetic energy from the battery carrier to the vehicle body upon movement of the battery carrier due to a collision of the vehicle, the collision releasing restriction of movement of the battery carrier applied by the movement-restricting member. While the battery disposed in the vehicle involves a corresponding increase in kinetic energy which acts on the vehicle body, the present body structure minimizes the transfer of such increased kinetic energy to the vehicle body upon collision of the vehicle.

Body structure for electric vehicle

A structure for arranging an auxiliary component of an electric vehicle has an auxiliary-component moving device for moving an auxiliary component disposed in a front body such that an overall length of the auxiliary component becomes less than an original overall length of the auxiliary components in a case where the front body is compressed and deformed. It is possible to reduce the amount of an impact load which is transmitted from an object located in front of the vehicle to a vehicle compartment by means of the auxiliary component.

Structure for arranging auxiliary components of an electric vehicle

A front body section of a vehicle which is provided with a front-side member and a crush box. The crush box includes a front section and a rear section, which are disposed in front of the front-side member so as to be axially aligned and connected thereto. An upper plate, a lower plate, an outer plate, and an inner plate, all of which form the front section, are prepared so as to provide a lower level of total plastic characteristic, when under load, than those plate members which form the rear section. The crush box thereby exhibits a total plastic characteristic, when under load, in two stages.
