FORMULA GREEN Page 16 RULE BOOK FORMULA GREEN 2015 T3.21.7 Where the standard IA is used but does not comply with edge distance limits of rule T3.21.6 and does not include a diagonal brace, physical testing must be carried out to prove that the Anti-Intrusion Plate does not permanently deflect more than 25.4mm (1.00 inch) T3.22 Impact Attenuator Data Requirement T3.22.1 All teams, whether they are using their own design of IA or the “standard” FSAE Impact Attenuator, must submit an Impact Attenuator Data Report using the Impact Attenuator Data (IAD) Template found at “Downloads” at http://www.fsaeonline.com. T3.22.2 The team must submit test data to show that their Impact Attenuator Assembly, when mounted on the front of a vehicle with a total mass of 300 kg (661 lbs.) and run into a solid, non-yielding impact barrier with a velocity of impact of 7.0 meters/second (23.0 ft/sec), would give an average deceleration of the vehicle not to exceed 20 g’s, with a peak deceleration less than or equal to 40 g’s. Total energy absorbed must meet or exceed 7350 Joules. NOTE 1: These are the attenuator functional requirements not test requirements. Quasi-static testing is allowed. NOTE 2: The calculations of how the reported absorbed energy, average deceleration, and peak deceleration figures have been derived from the test data MUST be included in the report and appended to the report template. T3.22.3 Teams using a front wing must prove the combined Impact Attenuator Assembly and front wing do not exceed the peak deceleration of rule T3.22.2. Teams can use the following methods to show the designs does not exceed 300 kg times 40g or 120 kN: a. Physical testing of the Impact Attenuator Assembly with wing mounts, links, vertical plates, and a structural representation of the aerofoil section to determine the peak force. See fsaeonline.com FAQs for an example of the structure to be included in the test. b. Combine the peak force from physical testing of the Impact Attenuator Assembly with the wing mount failure load calculated from fastener shear and/or link buckling. c. Combine the Standard Impact Attenuator peak load of 95kN with the wing mount failure load calculated from fastener shear and/or link buckling. T3.22.4 When using acceleration data, the average deceleration must be calculated based on the raw data. The peak deceleration can be assessed based on the raw data, and if peaks above the 40g limit are apparent in the data, it can then be filtered with a Channel Filter Class (CFC) 60 FORMULA GREEN Page 17 RULE BOOK FORMULA GREEN 2015 (100 Hz) filter per SAE Recommended Practice J211 “Instrumentation for Impact Test”, or a 100 Hz, 3rd order, low pass Butterworth (-3dB at 100 Hz) filter. T3.22.5 A schematic of the test method must be supplied along with photos of the attenuator before and after testing. T3.22.6 The test piece must be presented at technical inspection for comparison to the photographs and the attenuator fitted to the vehicle. T3.22.7 The test data and calculations must be submitted electronically in Adobe Acrobat ® format (*.pdf file) to the address and by the date provided in the Action Deadlines provided on the relevant competition website. This material must be a single file (text, drawings, data or whatever you are including). T3.22.9 Teams that submit their Impact Attenuator Data Report after the due date will be penalized 10 points per day up to a maximum of 50 points, which will be taken off the team’s Total Score. T3.22.10 Impact Attenuator Reports will be evaluated by the organizers and the evaluations will be passed to the Design Event Captain for consideration in that event. T3.22.11 During the test, the Impact Attenuator must be attached to the Anti-Intrusion plate using the intended vehicle attachment method. The anti-intrusion plate must be spaced at least 50 mm (2 inches) from any rigid surface. No part of the anti-intrusion plate may permanently deflect more than 25.4 mm (1 inch) beyond the position of the anti-intrusion plate before the test. The anti-intrusion plate must be attached to a structurally representative section of the intended chassis that extends a minimum of 50.8mm (2 inches) away from the Front Bulkhead. NOTE 1: The 25.4 mm (1 inch) spacing represents the front bulkhead support and insures that the plate does not intrude excessively into the cockpit NOTE 2: A solid block of material in the shape of the front bulkhead is not “structurally representative”. A structurally representative test fixture should have a similar cross sectional moment of inertia as the actual front bulkhead. T3.22.12 Dynamic testing (sled, pendulum, drop tower, etc.) of the impact attenuator may only be done at a dedicated test facility. The test facility may be part of the University but must be supervised by professional staff or University faculty. Teams are not allowed to construct their own dynamic test apparatus. Quasi-static testing may be performed by teams using their universities facilities/equipment, but teams are advised to exercise due care when performing all tests. FORMULA GREEN Page 18 RULE BOOK FORMULA GREEN 2015 T3.22.13 Standard Attenuator – An officially approved impact attenuator can be found in Appendix T-3. Teams that choose to use the ”standard” FSAE Impact Attenuator and the corresponding mounting details need not submit test data with their IAD Report. However, the other requirements of the IAD Report must still be submitted including, but not limited to: a. Use of the standard IA Data Report form. b. Photos of the team’s actual attenuator with evidence that it meets the design criteria given in Appendix T-3, e.g., a receipt or packing slip from the supplier. c.

Driver must re-enter the track at or prior to the missed gate or a twenty (20) second penalty will be assessed. Penalties will not be assessed for accident avoidance or other reasons deemed sufficient by the track officials. Missed Slalom- Missing one or more gates of a given slalom will be counted as one "off-course" per occurrence. Each occurrence will incur a twenty (20) second penalty. Note- The track layout may change as per the track layout. 2.2.5. Endurance and Efficiency - The following are general guidelines for conducting the endurance and efficiency event. The organizers reserve the right to establish procedures specific to the conduct of the event at the site. Endurance Objective (200 points) - The Endurance Event is designed to evaluate the overall performance of the vehicle and to test the vehicle’s reliability. Efficiency test (125 points) - The efficiency test is based on the amount of energy consumed during the endurance heat. Course speeds can be estimated by the following course specifications. Average speed should be 45 km/hr to 55 km/hr with top speeds of approximately 70 km/hr. Procedure- The event will be run as a single heat approximately 27.6 km (12 Laps) long. Teams are not allowed to work on their vehicles during the heat. A driver change can be made during a two (2) minute period at the midpoint of the heat. Wheel-to-wheel racing is prohibited. Passing another vehicle may only be done in an established passing zone. FORMULA GREEN Page 42 RULE BOOK FORMULA GREEN 2015 Vehicle Starting/Restarting-The vehicle must be capable of starting / restarting without external assistance at all times once the vehicle has begun the heat. If a vehicle stalls out on the track, it will be allowed one (1) lap by the car that is following it (approximately one (1) minute) to restart. If a vehicle has a restart problem at the end of Driver Change, it will be allowed a further two (2) minutes to restart the motor. If restarts are not accomplished within the above times, the car will be deemed disabled and scored DNF for the heat. Driver Changing Procedure- Elapsed time will begin when Driver A enters the course and crosses the timing line. Driver A will drive for half of the total laps (6), and pull into the driver change area Two (2) minutes are allowed for the team to change drivers. Driver 1 will exit the vehicle and any necessary adjustments will be made to the vehicle to fit Driver B (seat cushions, pedal position, etc.). Only three (3) team members, including the driver or drivers, will be allowed in the driver change area, and only the tools necessary to change drivers and/or tires will be carried into this area (no tool chests etc.). Extra people entering the driver change area will result in a 20 point penalty to the final endurance score for each extra person entering the area. Driver 2 will then be secured in the vehicle. The driver change area will be placed such that the timing system will see the driver change as an extra long lap. Unless this driver change takes longer than two minutes, this extra long lap will not count. If the driver change takes longer than two minutes, the extra time will be counted into the final time. Driver 2 will drive for rest of the laps (6) and elapsed time will stop when the car completes the total 12 laps. Vehicle Breakdown and Stalls- If a vehicle breaks down it will be removed from the course and will not be allowed to re-enter the course. If a vehicle stalls, or ingests a cone, etc., it will be allowed to restart and re-enter the course where it went off, but no work may be performed on the vehicle. If a car stalls and cannot be restarted without external assistance, the track workers will push the car clear of the track. At the discretion of event officials, two (2) team members may retrieve the car under direction of the track workers. Endurance Minimum Speed Requirement- If a car is unable to maintain lap times within 133% of the fastest lap time for the course, and then it must exit immediately. Disqualification for failure to maintain the minimum speed will be made at the discretion of the Director of Operations. Endurance Lap Timing- Each lap of the endurance event will be individually timed either by electronic means, or by hand. The time for an individual heat will be determined by subtracting the extra long lap for the driver change from the total time and adding any penalty points. FORMULA GREEN Page 43 RULE BOOK FORMULA GREEN 2015 Penalties Cones Down Or Out- Two (2) seconds per cone. This includes cones before the start line and after the finish line. Off Course-For an OC, the driver must re-enter the track at or prior to the missed gate or a twenty (20) second penalty will be assessed. Missed Slalom- Missing one or more gates of a given slalom will incur a twenty (20) second penalty. Penalties for Moving ViolationsFailure to obey a flag: 1 minute Over Driving (After a closed black flag): 1 Minute Vehicle to Vehicle contact: DISQUALIFIED Out of Order- Running out of order – two (2) minute penalty Mechanical Problem- No additional penalty other than the time lost to ensure that the car is safe to continue. Reckless or Aggressive Driving- Any reckless or aggressive driving behaviour (such as forcing another car off the track, refusal to allow passing, or close driving that would cause the likelihood of car contact) will result in a black flag for that driver. When a driver receives a black flag signal, he must proceed to the penalty box to listen to a reprimand for his driving behaviour. The amount of time spent in the penalty box will vary from one (1) to four (4) minutes depending upon the severity of the offense. Inexperienced Driver- The Chief Director of Operations may disqualify a driver if the driver is too slow, too aggressive, or driving in a manner that, in the sole opinion of the event, officials, demonstrates an inability to properly control their car resulting in a DNF.
