Our test results indicated that the specimen satisfied the requirements of B3. The drawing applies for the – competition year. Teams should use good engineering practice and calculations to determine the best mounting method for their vehicle. There is one clarification, however. Deflections must be less than the These calculations or test data should be included in the impact attenuator data submission and should include predicted strength and deflections.

Standard Impact Attenuator
If the attenuator is made of more than one piece of foam those pieces must be glued together using a structural adhesive that is compatible with the Mpadx foam. Examples of good documentation include a receipt from that competition year, a packing slip or letter of donation. Deflections must be less than the Attachment methods are important for providing for impacts that occur at an angle.
Segments may not be stacked without glue. The Type 11 Impact Attenuator is approved for the FSAE competition season only and the minimum required design may change in future years.
Since the required testing is done with the attenuator crushing moaxx to the vehicle axis mounting is really evaluated. Teams should use good engineering practice and calculations to determine the best mounting method for their vehicle.
Standard Impact Attenuator – Formula Seven
Are we required to submit an impact attenuator data submission by the action deadline on the website? The mounting shown on the part print is a suggested method that could be used. What should be included in this submission?
These calculations or test data should be included in the impact attenuator data submission and should include predicted strength and deflections. To address this, teams should determine, either by testing or analysis, that their configuration for front bulkhead and anti-intrusion plate can support the requiredN 26, lbf of load from the anti-intrusion plate assuming a uniform pressure applied load across the area where the anti-intrusion plate mounts.
Yes, please see B3.
Our test results indicated that the specimen satisfied the requirements of B3. There is one clarification, however. However, teams have the burden of proof to show their foam is the required material. The technical inspectors may choose to verify the dimensions and the material and have the authority to conduct any measurements, inspections or tests they feel are necessary.
The drawing applies for the – competition year. There is no change from the Type 12 Impact attenuator.
The drawing applies for the competition year. Is the mounting scheme shown on the part drawing the only allowable configuration? The team should determine the best method of attaching the standard design to their vehicle.
