Notes:

Complete rework of design from the original CAD.

This pad is better suited to fit around the drivers foot and prevent foot slippage.

Overall safer.

 

Material: AISI 4130 Steel - Annealed at 865 C, Yield Strength: 460MPa (4.6 x 10E8 N/m^2)

Fixtures:

To restrict planar movement.

Interactions:

A virtual walls represent where the pad made contact with the break pedal and the bolt heads.

Loading (Perpendicular force):

Load of 311.6N directed perpendicularily on the face, multiplied by 2 for the safety factor (623.2N).

Loading (Angled force):

311.6N loaded at an angle of 30 degrees, with a safety factor of 2, 623.2N. This is to simulate the angle of the foot pushing the pedal pad.

Mesh:

 

Mesh control applied at the point of contact of the pad and the pedal.

Results (Perpendicular force):

 

Note: Rounding the corners may be a good idea to reduce stress. However, the DFM may be a little difficult

 

Results (Angled force):

 

Next steps:

  • Machine the pedal pad

  • Sim for different angles of force applied (depends on driver)

  • (any thing else?)
