3 Presentation Outline Form 1 Information and Submission Optional NCAP Testing MGA Flying Floor Equipment and Oblique Pole Test Methodology MGA ATD Seating Procedures Review 2011 Model Year NCAP Testing Procedures 2011 Model Year NCAP Injury Criteria Questions

4 Frontal NCAP Test vehicle impacts flat rigid barrier at 0 o Belted ATDs placed in both front outboard seating positions Test mode simulates headon collision with equal weight vehicle traveling at identical speed

5 MDB cart impacts side of test vehicle Both vehicles rotated to 27 o angle Belted ATDs placed in both struck-side outboard seating positions Similar to FMVSS 214D Simulates perpendicular impact with both vehicles in motion MDB Side NCAP

6 Similar to FMVSS 214 Rigid Pole 32kph (20mph) Test Speed Test vehicle positioned at 75 angle to direction of travel FMVSS 214 ES-2 or SID-IIs SID-IIs (ATD) placed in Driver seating position Intrusion into test vehicle is more severe than other test modes Oblique Pole NCAP

7 Form 1 Information Seating Position Seat track length, manufacturer s design seat back angle References (zeroed at sill) noted Correct Information D-Ring Position Fuel Tank Capacity and Draining Procedure Early delivery to NCAP will be critical for a smooth test process Special Instructions Prioritized parts removal list

8 Form 1 Information Disabling of Curtain Airbags NCAP, SINCAP Non-Struck Side Airbag disabling will be performed by manufacturer representatives on the test day Airbag disabling will be supervised by MGA personnel Frontal NCAP 5 th Percentile ATD Selection FTSS / Denton Dummy version should match manufacturer FMVSS 208 compliance test submission

9 Optional NCAP Testing Process Outline 1. Manufacturer request for optional test sent to NCAP 2. Letter of approval from NCAP to manufacturer and test lab 3. Vehicle selected by Alpha Technology Associate, Inc. 4. Selected test vehicle purchased by test lab All other items proceed identical to standard NCAP testing Form 1 Information provided to NCAP Vehicle purchase price and test costs are manufacturer responsibilities

10 Test Lab Selection Optional NCAP Testing Request for optional test submitted by manufacturer includes requested test lab Test laboratory must have current NCAP contract (MGA Research Corporation, Calspan, KARCO Engineering, Transportation Research Center, The Medical College of Wisconsin) Vehicle Selection NCAP selection of the vehicle to be purchased (Alpha Technology Associate, Inc.) Purchase and delivery to the selected test lab MGA will coordinate purchase and delivery

11 Optional NCAP Testing Test Scheduling MGA receives approval letter from NCAP MGA receives vehicle shipping information Available test dates will be offered to NCAP and manufacturer NCAP will determine test date, with manufacturer s preference considered Vehicle preparation typically begins 5 days prior to selected test date

12 Optional NCAP Testing Post-Test Deliverables Reports, Photos, Videos delivered to NCAP Manufacturer representatives will receive an occupant injury summary Test Vehicle Shipping and/or Destruction Test vehicle will remain at the test lab for 30 days after the test date Vehicles can then be destroyed or shipped back to the manufacturer Destruction and/or shipping costs are manufacturer responsibilities NCAP Acceptance and Ratings Publication All test information will be reviewed by NCAP and released to the public ( Early release of test data, videos, and photos to the vehicle manufacturer must be requested through NCAP

13 MGA Flying Floor

14 MGA Flying Floor

15 MGA Flying Floor

16 MGA Flying Floor The test vehicle is placed on the flying floor surface Onboard high-speed video and data acquisition equipment is mounted Test vehicle, flying floor, and ATD are transported to temperature-controlled preparation room

17 MGA Flying Floor Methodology ATD is positioned according to test procedure Laser is used to measure the horizontal offset of the ATD Head C.G. from the center of the test track Checkered tape is placed on the test vehicle to indicate the desired impact location

18 ATD Head C.G. offset measurement is transferred to the pole impact area Pole fixture is adjusted to match the ATD Head C.G. offset Tack placed on front surface of pole fixture will indicate actual impact location Tack location relative to the checkered tape place on the impact side of the vehicle will indicate impact point deviation MGA Flying Floor Methodology

19 MGA Flying Floor Methodology During towing, the test vehicle is restrained by abort straps connected to the nonstruck side Straps prevent the vehicle from leaving the flying floor surface if a test abort is required Limit switches on the underside of the flying floor are triggered 100 feet prior to impact, releasing straps

20 MGA Flying Floor Methodology Vehicle impact to pole occurs prior to flying floor deceleration Ensures proper test vehicle speed, orientation, and impact location Deceleration of the flying floor triggers on-board braking system Brakes prevent the flying floor from rebounding away from the impact area Test vehicle remains on the flying floor surface after the event

21 MGA Flying Floor Methodology Floor Surfaces Main floor area covered with low-friction Teflon No modification to the vehicle Rear floor area coated with high-friction paint Adjustable wheel chock at left rear to prevent fore-aft vehicle movement prior to impact

22 Frontal NCAP: 50th Percentile To follow FMVSS 208 seating interpretation 1. Mid seat fore-aft travel Seating Procedures Note: seat fore-aft travel length is determined using ANY controls that affect fore-aft movement 2. Lowest height 3. Manufacturer s suggested seat cushion angle Only if seat cushion adjusts independent of seat 4. Seat back angle determined by manufacturer s nominal design riding position for 50 th percentile adult male Frontal NCAP: 5 th Percentile To follow FMVSS 208 seating interpretation 1. Mid cushion angle 2. Mid height (with mid-angle maintained) 3. Forward-most seat track (with mid-angle maintained) Note: seat track length is determined using only the controls that primarily move the seat fore and aft 4. Seat back angle determined by ATD head level

23 SINCAP: ES-2re Seating Procedures To follow FMVSS 214 seating interpretation 1. Mid cushion angle 2. Lowest height (with mid-angle maintained) 3. Mid seat track (with mid-angle maintained) Note: seat track length is determined using only the controls that primarily move the seat fore and aft 4. Seat back angle determined by manufacturer s nominal design riding position for 50 th percentile adult male SINCAP: SID-IIs 1. Mid cushion angle 2. Lowest height (with mid-angle maintained) 3. Rearward-most seat track (with mid-angle maintained) Note: seat track length is determined using only the controls that primarily move the seat fore and aft 4. Seat back angle determined by ATD head level

24 Seating Procedures SINCAPP: SID-IIs 1. Mid cushion angle 2. Mid height (with mid-angle maintained) 3. Forward-most seat track (with mid-angle maintained) Note: seat track length is determined using only the controls that primarily move the seat fore and aft 4. Seat back angle is determined by ATD head level

25 Typical Power Seat Adjustment

26 Typical Power Seat Adjustment At starting position, SCRL angle is 0.0 for simplicity Seat Cushion Reference Point (SCRP) is located mm from front edge of seat cushion Seat Cushion Reference Line (SCRL) is drawn through the SCRP Seat track is moved to the full-rearward position Front and Rear Controller are moved to the full-down position

27 Typical Power Seat Adjustment Both the Front and Rear Controller have an effect on the SCRL angle Both adjustments are considered seat cushion angle adjustments Seat Back Angle Controller and Lumbar Adjustment are not used during seat cushion adjustment

28 Typical Power Seat Adjustment Front Controller is moved to the full down position Rear Controller is moved to the full up position The minimum angle of the SCRL can now be measured SCRL angle is measured to be -3.2

29 Typical Power Seat Adjustment Front Controller is moved to the full up position Rear Controller is moved to the full down position The maximum angle of the SCRL can now be measured SCRL angle is measured to be 5.0

30 Typical Power Seat Adjustment SCRL is placed at the mid angle of the minimum and maximum angles ( ) / 2 = 0.9 This angle must be maintained when adjusting seat cushion height to desired position Fore/Aft Seat Track length is determined with the seat cushion set to the required angle and height
