All prices are exclusive of VAT. Mid-sagittal plane of a dummy means a longitudinal vertical plane passing through the seating reference point of a designated seating position.
Vehicles manufactured by final stage manufacturers on or after September 1, shall, except as provided in S6.
Brace means a fixed diagonal structural member in an open body vehicle that is used to brace the roll-bar and that connects the roll-bar to the main body of the vehicle structure. If a target is on a seat belt anchorageregulatikn if the seat belt anchorage is adjustable, tests are conducted with the anchorage adjusted to a point midway between the two extreme adjustment positions.
Target FH2 is located at the intersection of Plane 21 and the upper vehicle fmvws, halfway between a transverse vertical plane Plane 22 through Point 10 and a transverse vertical plane Plane 23 through the intersection of Plane 21 and Line 3.
The B-pillar reference point Point BPR is the point located at the middle of the line from Point 3 to Point 4 in Plane 7, measured along the f,vss interior surface. The approach angles specified in S8.
Locate a horizontal plane Plane 11 half-way between Plane 9 rwgulation Plane Code What Cites Me. The HIC d shall not exceed when calculated in accordance with the following formula:.
For front outboard designated seating positions, the head center of gravity with the seat in its forwardmost adjustment position CG-F1 is located horizontally forward of CG-F2 by the distance equal to the fore-aft distance of the seat track. Windshield trim means molding of any material between the windshield glazing and the exterior roof surface, including material that covers a part of either the windshield glazing or exterior roof surface.
In a test in which the test vehicle is striking its left side, the dummy is to be configured and instrumented to strike on its left side, in accordance with subpart M of part If the adjacent door s or daylight opening s are equidistant to Plane 28, Point 18 is located on the vehicle interior at the intersection of Plane 28 and either horizontal plane through the highest point of each door or daylight opening.
All major automakers have different categories of dynamic testing methods as part of their design process in validating their designs against the FMVSS requirement. Target SR2 is located at the middle of the line between Point 13 and Point 14 in Plane 26, measured along the vehicle interior. Seat belt anchorage means any component involved in transferring seat belt loads to the vehicle structure, including, but not limited to, the attachment hardwarebut excluding webbing or straps, seat frames, seat pedestals, and the vehicle structure itself, whose failure causes separation of the belt from the vehicle structure.
A commercially available CAE process automation tool was used to automate these steps and generate a head impact simulation model. The section you are viewing is cited by the following CFR sections. Locate a horizontal plane Plane 9 which passes through the lowest point of the daylight opening forward of the pillar. The focus of the seminar is on the development process and the development tools and methods.
Locate the point Point 21 on the vehicle interior at the intersection of the horizontal plane passing through the highest point of the forward door opening and a transverse vertical plane Plane 32 tangent to the rearmost edge of the forward door, as viewed laterally with the adjacent door open.
Locate the point Point 13 at the intersection of Plane 26 and the upper edge of the forwardmost door opening. Using the same method, draw a line from Point b to Point d. Locate a horizontal plane Plane 40 half-way between Plane 38 and Plane Construct a line in the plane that contains the rearward point of the front door daylight opening and is perpendicular to the longitudinal vehicle centerline.
Measuring along the vehicle exterior surface, locate a point Point 1 on Line 1 that is mm inboard of the intersection of Line 1 and a vertical plane tangent to the vehicle at the outboardmost point on Line 1 with the vehicle side door open.
The maximum horizontal approach angle for the right A-pillar impact equals the angle formed by that line and the X-axis of the vehicle measured counterclockwise.
A 0 degree vertical vector in Table I coincides with the horizontal plane and a vertical vector of greater than 0 degrees in Table I makes an upward angle of the same number of degrees with that plane.
If the horizontal line is tangent to the periphery at more than one point at any location, the most inboard point is the door opening. Locate a horizontal plane Plane 34 that passes through the lowest point of the adjacent daylight opening forward of the door frame.
The load placed in the cargo area shall be centered over the longitudinal centerline of the vehicle. For front outboard designated seating positions, the head center of gravity with the seat in its rearmost normal design driving or riding position CG-F2 is located mm rearward and mm upward from the seating reference point.
Locate the point Point 6 at the intersection of the interior roof surface, Plane 12 and the plane, described in S8.
Head Impact on Vehicle Interiors: FMVSS and UN R21 – Empowering Engineers
The Y coordinate is negative to the left of the X-Z plane and positive to the right. Determination of impact locations in a vehicle Development process and methods Solving of conflicts of objectives Typical deformation paths, padding materials.
The minimum horizontal approach angle for the left seat belt mounting structure equals the angle formed by that line and the X-axis of the vehicle measured counterclockwise. For altered vehicles and vehicles built in two or more stages, including ambulances and motor homes, any target located rearward of a vertical plane regulagion behind the seating reference point of the driver ‘s designated seating position tests fmvws altered vehicles and vehicles built in two or more stages do not include, within the time period for measuring HIC dany free motion headform contact with components rearward of this plane.
The intersection of Plane 1 and the vehicle exterior regulattion is Line 1.
Target BP3 is located in accordance with this paragraph. The rearmost pillar reference point Point RPR is at the midpoint of the line between Point 7 and Point 8, measured along the vehicle interior.
S5 Requirements for instrument panels, seat backs, interior compartment doors, sun visors, and armrests. The rigid pole shall be stationary. Initially, position adjustable seat backs in the manner specified in S8. LS-DYNA is one of the most commonly used non-linear solvers in the automotive industry, particularly for safety related simulations such as the head impact of automotive interiors.
Locate a longitudinal vertical plane Plane 18 that passes through Point 9. The load placed in the cargo area is centered over the longitudinal centerline of the vehicle.
With product development PD cycles becoming more compressed, CAE has assumed rsgulation more significant fmvsx in early, advanced design and structural evaluation.
