A method for simulating deformation of a body element of a motor vehicle that occurs during an impact event includes providing a model of the body element that includes an initial load distribution pattern. A first simulation output is generated during a first portion of the impact event using the initial load distribution pattern and includes data indicative of the deformation of the body element. Whether a portion of the body element is in a failure condition is determined based on the first simulation output. If a failure condition is determined, the load distribution pattern of at least a portion of the body element is updated, and a second simulation output including data indicative of the deformation of the body during a second portion of the impact event is generated using the updated load distribution pattern.

Method for door side intrusion simulation with progressive failures

Disclosed herein are embodiments of vehicles and vehicle body assemblies incorporating slide rail reinforcements. One embodiment of a vehicle body assembly comprises an inner body panel and an outer body panel spaced a distance from the inner body panel in an outboard direction of a vehicle. The outer body panel has an outer surface and an opposing inner surface. An elongated slide track is mounted on the outer surface of the outer body panel. A force distribution member has a support surface fixed to the inner surface of the outer body panel directly opposite a portion of the elongated slide track and first and second distribution legs extending from the support surface and fixed to the inner body panel.

Slide rail force distribution member

A vehicle sliding door structure includes an inner door panel, an outer door panel, a reinforcing bracket and a first bulkhead. The inner door panel has a vertically oriented sash section extending along an outboard facing surface thereof adjacent to a rearward side of an outer peripheral edge thereof. The sash section has a latch mechanism supporting part proximate a mid-region of the rearward side of the outer peripheral edge. The outer door panel is fixed to the outer peripheral edge of the inner door panel. The reinforcing bracket is fixedly attached to the outboard facing surface of the inner door panel along a region of the sash section that extends from below the latch mechanism supporting part to above the latch mechanism supporting part. The first bulkhead is fixedly attached to the reinforcing bracket and extends from the reinforcing bracket toward the outer door panel.

Vehicle sliding door structure

A vehicle sliding door structure includes an inner door panel, an outer door panel, a reinforcing bracket and a first bulkhead. The inner door panel has a vertically oriented reinforced section extending along an outboard facing surface thereof adjacent to a rearward side of an outer peripheral edge thereof. The reinforced section has a latch mechanism supporting part proximate a mid-region of the rearward side of the outer peripheral edge. The outer door panel is fixed to the outer peripheral edge of the inner door panel. The reinforcing bracket is fixedly attached to the outboard facing surface of the inner door panel along a region of the reinforced section that extends from below the latch mechanism supporting part to above the latch mechanism supporting part. The first bulkhead is fixedly attached to the reinforcing bracket and extends from the reinforcing bracket toward the outer door panel.

A vehicle body structure has a first structural member that at least partially defines an upper side of a door opening and a second structural member that extends downward from the first structural member and at least partially defines one side of the door opening. An elongated track member is attached on the first structural member. A sliding door is movably supported on the track member for movement along the track member between a closed position and an open position. A stopper bracket is rigidly attached on the second structural member. The stopper bracket is dimensioned and configured to absorb impacting forces of the sliding door as the sliding door moves from the closed position to the open position. The stopper bracket is rigidly attached to the track member such that the impacting forces are at least partially transmitted to the track member.
