T3.29 Monocoque Inspections

Читайте также:
  1. T3.40 Monocoque Attachments

Due to the monocoque rules and methods of manufacture it is not always possible to inspect all aspect

of a monocoque during technical inspection. For items which cannot be verified by an inspector it is the responsibility of the team to provide documentation, both visual and/or written, that the


 

 

requirements have been met. Generally the following items should be possible to be confirmed by the technical inspector:

 

• Verification of the main hoop outer diameter and thickness where it protrudes above the monocoque

• Visual verification that the main hoop goes to the lowest part of the tub, locally. This may be difficult as the tube is allowed to be integrated into the laminate but there is often a contour that comes from the tube that is visible.

• Verify mechanical attachment of main hoop to tub exists and matches the SES, at all points shown on the SES.

• Verify visually or by feel that the front roll hoop is installed. Verify mechanical attachment (if included) against the SES.

 

Items such as the size and composition of the front roll hoop, when integrally bonded to the monocoque, must be proven with documentation that shows dimensions on the tubes and pictures of the dimensioned tube being included in the layup. A team found to be improperly presenting any evidence of the manufacturing process will be barred from competing with a monocoque through at least the following year.

 

T3.30 Monocoque Buckling Modulus – Equivalent Flat Panel Calculation

When specified in the rules, the EI of the monocoque must be calculated as the EI of a flat panel with the same composition as the monocoque about the neutral axis of the laminate. The curvature of the

panel and geometric cross section of the monocoque must be ignored for these calculations.

 

Note: Calculations of EI that do not reference T3.30 may take into account the actual geometry of the monocoque.
