PART AF - ALTERNATIVE FRAME RULES ARTICLE 1: GENERAL REQUIREMENTS

These alternative structural requirements are intended to provide teams an alternative approach to the existing rules. The goal of these alternative rules is to provide a simpler alternative for monocoque designs and provide expanded design freedom for space frames and monocoques alike. The intent is not to alter allowable structures but to change the requirement process for showing compliance with the rules.

Note: Generally SI units are used in these alternative frame rules with some dual references.

AF1.1 Unless listed below under section AF7 “Non-Applicable Rules” all requirements of the rest of the rules apply in these alternative requirements.

AF1.2 The AF Rules are considered a work in progress. As such, the Rules Committee and reviewers of the SRCF (below) may, at any time, amend and clarify these rules to maintain the spirit in which they were written and close any unintended loop holes.

AF1.3 These rules are recommended for existing teams who have experience designing, constructing and competition with vehicles in the past. There is no experience requirement.

AF1.4 Notice of Intent - Teams planning to build a vehicle to this alternative rule set for entry into a North American competition must notify the Rules Committee of their intent by November 1, 2010. Include a short paragraph detailing your team’s finite element capability and showing you can meet all analytical requirements specified in this Appendix. Your “Notice of Intent” should include the email addresses and phones numbers of the team members who can answer any questions the Committee may have about your proposal.

The notice of intent submission should also include a brief report analyzing the sample structures problem posted to the SAE website. Please include a brief text description of your analysis approach, what software you used, the element types, mesh quality and boundary conditions that were used in this analysis. The results provided will be used to assess the team’s capability to perform this type of structural analysis.

AF1.5 The Rules Committee will remain in contact with teams using the AF rules to help them develop and document their frames and to give the Committee data and feedback that can be used to refine the AF rules.

AF1.6 Notice of Intent – Procedure

A. Address – Teams using the AF Rules for a 2012 competition in North America must submit

their “Notice of Intent” to the FSAE Rules committee at:[e-mail].

B. Due Date – “Notices of Intent” to use the AF Rules for to 2012 vehicle must be submitted to the

Rules Committee by 11:59 pm November 1, 2011.

C. Acknowledgement – The Rules Committee will review your “Notice of Intent” and respond

with their approval/disapproval within 15 days.

ARTICLE 2: STRUCTURAL REQUIREMENTS CERTIFICATION FORM (SRCF)

Since there is no baseline steel design in this alternative rule set, the team must show they are meeting

the functional structural requirements.

When the Alternate Frame Rules are used the Structural Requirements Certification Form (SRCF)

supersedes the Structural Equivalency Spreadsheet (SES) which does not have to be submitted.

AF2.1 SRCF - Submission Process

A. Address – SRCFs must be submitted to the officials at the competition you are entering at the address indicated on the competition website or shown in the Appendix.

B. Due Date and Late Submission Penalty – SRCFs must be submitted no later than the due date

specified on the competition website (For US events reference “Action Deadlines”). Teams

that submit their SRCF after the relevant due date will be penalized ten (10) points per day up

to a maximum of fifty (50) points which will be deducted from the team’s total score.

C. Acknowledgement – North American Competitions – SRCFs submitted for vehicles entered into competitions held in North America will be acknowledged upon receipt.

ARTICLE 3: DEFINITIONS

The following additional definitions apply throughout the Rules document in addition to the ones

listed in T3.3

· Failure - Tensile, compressive, shear load or buckling critical load lower than the specified load. All failure modes have to be considered for every load case.

· Directions – The following coordinate system and labeling convention is used within these rules

o Longitudinal (X)

o Transverse (Y)

o Vertical (Z)
