Abstract:
A vehicle includes a body structure and a frame rail assembly. The frame rail assembly extends forward from the bulkhead along a longitudinal centerline. The frame rail assembly includes a frame rail defining a rail axis and a reinforcing member. The frame rail defines a longitudinally extending seam and the frame rail extends forward from the bulkhead along the longitudinal centerline. The frame rail further defines an end portion. The reinforcing member is secured to the frame rail at the end portion to increase a stiffness of the frame rail at the end portion. The reinforcing member is configured to limit a stress at the seam, transverse to the rail axis, resulting from a load applied to the end portion of the frame rail and laterally offset from the longitudinal centerline.
Abstract:
A body structure of a vehicle includes a bulkhead, and a frame rail extending forward from the bulkhead along a longitudinal centerline. A powertrain system is disposed laterally inboard of the frame rail relative to the longitudinal centerline. The frame rail includes a flared section, a splayed section, and a reinforcing member. The flared section curves laterally outboard, away from the longitudinal centerline. The splayed section includes a variable cross sectional area that increases with an increase in distance from the bulkhead. The reinforcing member is operable to increase lateral stiffness in the frame rail, in a direction transverse to the longitudinal centerline. The frame rail is operable to deform into contact with the powertrain system in response to a load applied to a forward end of the body structure and laterally offset from the longitudinal centerline, to generate a lateral force in the body structure.
