Locate the point Point 3 on the vehicle interior at the intersection of the horizontal plane passing through the highest point of the forwardmost door opening and the centerline of the width of the B-pillaras viewed laterally. Except as provided in S5. Target SR3 is located at the middle of the line between Point 15 and Point 16 in Plane 27, measured along the vehicle interior surface. With product development PD cycles becoming more compressed, CAE has assumed a more significant role in early, advanced design and structural evaluation.
Head Impact on Vehicle Interiors: FMVSS and UN R21 – Empowering Engineers
For rear outboard designated seating positions, the head center of gravity CG-R is located mm rearward, relative to the seat orientation, and mm upward from the seating reference point. More limitations on accuracy are described at the GPO site. This course is available as an in-house seminar. The top, if any, of convertibles and open-body type vehicles is in the closed passenger compartment configuration.
Each interior compartment door assembly located in an instrument panel, console assembly, seat back, or side panel adjacent to a designated seating position shall remain closed when tested in accordance with either S5.
This has given rise to a corresponding number of knee impact simulations performed at various stages of product development. A 0 degree horizontal vector and a degree horizontal vector point in the positive X direction; a 90 degree horizontal vector points in the positive Y direction; a degree horizontal vector points in the negative X direction; and a horizontal degree vector points in the negative Y direction.
The partsubpart M, test dummy is initially positioned in the front outboard seating position on the struck side of the vehicle in accordance with the provisions of S Target SB3 is located on the seat belt mounting structure and in Plane 43 at the location closest to CG-R, as appropriate.
Locate the point Point 22 at the intersection of the interior roof surface, Plane 32, and the plane, described in S8. The load placed in the cargo area is centered over the longitudinal centerline of the vehicle.
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. 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. Stiffener means a fixed overhead structural member that connects one roll-bar to another roll-bar or to a header of any open body vehicle or convertible.
Roll-bar means a fixed overhead structural member, including its vertical support structure, that extends from the left to the right side of the passenger compartment of any open body vehicles and convertibles. For components for which Table 1 specifies a range of angles, the headform launching angle is within the limits determined using the procedures specified in S8. Locate a horizontal plane Plane 36 half-way between Plane 34 and Plane 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.
Occupant knee impact simulations are performed in the automotive industry as an integrated design process during the course of instrument panel IP development.
If a seat belt anchorage is located on the roll-barTarget RB2 is any point on the anchorage. Additionally, any interior compartment door located in an instrument panel or seat back shall remain closed when the instrument panel or seat back is tested in accordance with S5. We are using cookies to give you the best experience on our site. Internationally there are two important regulations regarding the design of interiors, such as cockpits, roof and door liners: 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.
It is not guaranteed to be accurate or up-to-date, though we do refresh the database weekly. The midsagittal plane of the headform is designated as Plane S.
Head Impact on Vehicle Interiors: FMVSS 201 and UN R21
The requirements do not apply to any target that cannot be located using the procedures of S Measure the longitudinal distance between the rearmost point on the dummy head and this line. Locate a horizontal plane Plane 35 half-way between Plane 33 and Plane Locate the point Point 23 on refulation vehicle interior, at the intersection of the horizontal plane through the highest point of the highest adjacent door opening or daylight opening if there is no adjacent door opening and the center line of the width of the fnvss door frameas viewed laterally with the doors in the closed position.
The approach angles specified in S8. The rigid pole shall be stationary. The vehicle shall be tested and the targets specified in S10 located under the following conditions. Movable windows and vents shall be placed in the fully open position. Determination of impact locations in a vehicle Development process and methods Solving of conflicts of objectives Typical deformation paths, padding materials. The X-Y plane is the horizontal zero plane parallel to the ground.
Regulqtion roof linkage mechanism means gmvss anchorage, fastener, or device necessary to deploy a convertible roof frame. Occupant head impact simulations on automotive instrument panels IP are routinely performed as part of an integrated design process during the course of IP development. If the anchorage has distinct adjustment positions, none of which is midway between the two extreme positions, tests are conducted with the anchorage adjusted to the nearest position above the midpoint of the two extreme positions.
Locate a transverse vertical plane Plane 12 passing through Point 5. Target BP3 is the point located in Plane 10 and on the interior surface of the B-pillarwhich is closest to CG-F 2 for the nearest seating position.
Srikanth Krishnaraj – Profile – SAE International
Target FH2 is located at the intersection of Plane 21 and the upper vehicle interior, 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. Determine the intersection points, if they exist, of the small sphere surface, the horizontal plane, and the vehicle interior surface.
The X coordinate is negative forward of the Y-Z plane and positive to the rear. Although it was initially developed for metals, it is regjlation used for polymers as well.
