Locate a transverse vertical plane Plane 12 passing through Point 5. Locate the horizontal plane Plane 4 which is 88 mm below Plane 3.
Locate a horizontal plane Plane 34 that passes through the lowest point of the adjacent daylight opening forward of the door frame. The minimum horizontal approach angle for the left door frame equals the angle formed by that line and the X-axis of the vehicle measured counterclockwise.
Determine the intersection points, if they exist, of the small sphere surface, the horizontal plane, and the vehicle interior surface. Locate a horizontal plane Plane 41containing either CG-F2 or CG-R, as appropriate, for any outboard designated seating position whose seating reference pointSgRP, is forward of and closest to, the vertical regukation line of the width of the seat belt mounting structure as viewed laterally.
The front end of the line is designated as Point O. Reghlation is f,vss guaranteed to be accurate or up-to-date, though we do refresh the database weekly. If the seat belt mounting structure is below a horizontal plane passing through CG-F2 for the right seat, locate the point mm directly below that CG-F2 and locate a line formed by the shortest horizontal distance between that point and the right seat belt mounting structure.
Ambulance means a motor vehicle designed exclusively for the purpose of emergency medical care, as evidenced by the presence of a passenger compartment to accommodate emergency medical personnel, one or more patients on litters or cots, and equipment and supplies for emergency care at a location or during transport. 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. Target OD2 is the point located on the interior surface of the door frame at the intersection of Plane 40 and the center line of the width of the door frames, as viewed laterally, with the doors in the closed position.

LS-DYNA is one of the most commonly used non-linear solvers in fmvs automotive industry, particularly for safety related simulations such as the head impact of automotive interiors.
Except as provided in S5. This seminar is especially suited for engineers and technicians who work on the development of vehicle interior parts and who want to become familiar with the safety requirements that are relevant for these parts. The fmvsw 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.
Other pillar means any pillar which is not an A-pillara B-pillaror a rearmost pillar.
Both regulations stipulate requirements concerning the maximum head acceleration or the HIC in impacts on interior parts. Target SD is located at the middle of the line between Point 19 and Point 20 in Plane 29, measured along the vehicle interior.
Target RP2 is located in Plane 17 and on the pillar at the location closest to CG-R for the nearest designated seating position.
The minimum horizontal approach angle for the right A-pillar equals degrees minus the angle formed by that line and the X-axis of the vehicle, measured counterclockwise. The end of the line is designated as Point Regullation or Point R, as appropriate. 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.
National Highway Traffic Safety Administration. A-pillar means any pillar that is entirely fkvss of a transverse vertical plane passing through the seating reference point of the driver ‘s seat. 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.
The distance between Point M, as described in S8. On the striking side of the vehicle, place an impact reference line at the intersection of the vehicle exterior and a transverse vertical plane passing through the center of gravity of the head of the dummy seated in accordance with S8. 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.
Head Impact on Vehicle Interiors: FMVSS and UN R21 – Empowering Engineers
Any mfvss material between 13 and 32 mm from the panel surface shall have a minimum vertical height of not less than 25 mm. The HIC d shall not exceed when calculated in accordance with the following formula:. The forehead impact zone of the headform is determined according to the procedure specified in a through f. Although it was initially developed for metals, it is commonly used for polymers as well.

If the required distance cannot be achieved through movement of the seat, the seat back angle is adjusted even further forward until the 50 mm 2 inches distance is obtained or until the seat back is in its fully reghlation locking position. From numerous projects he has extensive experience in the field of occupant simulation and interior safety.
Daylight opening means, for openings on the side of the vehicle, other than a door openingthe locus of all points where a horizontal lineperpendicular to regulatoin vehicle longitudinal centerline, is tangent to the periphery of the opening. The maximum horizontal approach angle for the right refulation frame equals the angle formed by that line and the X-axis of the vehicle measured counterclockwise.
Locate a longitudinal vertical plane Plane 18 that passes through Point 9.
