Background

To start off, below is a video highlighting the general composition and design of a Formula SAE pedal box:

A pedal box is a system which is composed of an accelerator pedal and a brake pedal. Using these two pedals, the driver of the cart is then able to change the overall speed and acceleration that he/she is going.

The acceleration pedal is linked to the throttle of the car. Pressing down on this pedal then opens the throttle and lets more air go into the engine. Due to this, more fuel reacts with the air and the car moves quicker. (1)

The brake pedal works through a system which is seen below.
(2)
As can be seen, the brake pedal being pressed then presses on the labeled piston. This then pushes the fluid to the slave cylinder at the bottom. The slave cylinder then puts pressure on the wheels and slows the car down.

Week 6

Last week (Week 5), the group focused on preparing for the manufacturing of the pedal box. In order to do this, the design was made lighter and the group used the Finite Element Analysis (FEA) tool on Solidworks to see how well the material would hold up under force. This week (Week 6), the group finalized the preparations for manufacturing and sent parts to be created. In order to prepare for manufacturing, the group finalized the computer aided design of the pedal box, which can be seen below. In order to finalize this design, David added the real model of the balance bar to the assembly and added ball bearings to the pedals. These make the overall design more realistic when it comes to how the pedal box is actually going to function. Balance Bar (Left) || Ball Bearing (Bottom Right) Additionally, one problem that the group ran into was the forces on the brake pedal. It was determined that the screws holding the balance bar and master cylinder systems were under too much

Week 9

Last week (Week 8), the group focused on the machining of the throttle pedal, in addition to ordering the material for the adjustable slides. This week (week 9), the group manufactured the adjustable slides for the machine shop. Before thye physically manufactured the product, the overall design was updated by a senior member of Formula SAE. This design can be seen below. A small edge of metal was added to the side of the adjustable slide in order to absorb more force from the pedal box. Additionally, more metal was added beneath the bolts connecting to the chassis in order to add more support to the overall system. A photo of the product (halfway through manufacturing), as well as a video of the manufacturing, can be seen below:         Lauren made spacers for the gap between the pedals and pressed the bearings for the brake pedals. In order to do this, she first had to bore the hole for the brake pedal bearing. A video of machining this week can be seen below:

Week 5

Last week (Week 4), the group dove into the modelling of the pedal box, in addition to working on the Finite Element Analysis (FEA) which resulted from the design. Specifically, the FEA of the brake pedal was tested to see the strength of the material, and the pedal box slide was incorporated into the overall design. For this week (Week 5), more analysis was done on the pedal box as the group gets ready for its manufacturing. The final design of the pedal box is as such: To start off, the group focused on making the pedal box as light as possible. In order to achieve this goal this week, much of the group's attention was directed towards the throttle pedal. Last week (Week 4), David and Lauren both worked to find the appropriate thickness of the throttle pedal. While this is great for the overall design, it then makes the system marginally heavier. In order to counteract this, David put holes in the design and thinned the width of the throttle. This makes the overall system
