TEAM JURIC – DESIGN PART 3 – Seat, Steering, Universal Joints, Brakes & Bodywork

In Parts 1 & 2 we looked at
- Rule and Intent
- Layout and Architecture
- Dynamics
- Power Train
Originally, I was going to look at Chassis and Suspension Structures however, the content grew such that it’s now its own video, so it’s a 4-part Trilogy!

In this video, we will be looking specifically at:
Driver controls
• Seat
• Seat Belt
• Steering
• Universal Joints
• Steering Arm Rates
• Brake System
• Braking Weight Transfer
• Braking Tyre Forces
• Braking Acceleration
• Braking Torque
• Calliper Selection
• Line Pressures
• Master Cylinder Sizing
• Pedal Ratio and Foot Forces
• Pedal Box Brake and Accelerator

Bodywork
• 2d Faceting
• Buck/Male Mold
• Female Molds
• Bogging and Sanding
• Final Parts
• Perspex Wind Deflector

I start with the seat and cockpit layout; we’ve already covered the ergonomics but having a supportive seat holding you in place is key!

The steering system is broken down into each component.

I do a deep dive into the way Universal Joints work and how they fluctuate in speed with increased angle and joint phasing. Key takeaways are to have at least two at the same internal angles and 90 deg out of phase to make them a constant velocity joint!

Next, we design the entire braking system from braking potential, and tyre grip, to the selection of rotors, callipers, line pressures, master cylinders, pedal ratios, and foot forces.

The pedal box is broken down into what is important, STIFFNESS!!

Finally, a look at how I propose to make the beautiful, laborious bodywork. I’m sure you will all enjoy future videos of me block-sanding myself into oblivion!!

We hope you enjoy!
