Node Design Phase 1 Presentation

Presented by SD1/SD2/IV/SA

Our Goal

Node Design Pattern and substantiating theory.

Utilised for the design of all the Nodes throughout the chassis.

Initial Node used for Design

Original Node

3D Printed MaterialsAluminium Titanium

- AlSi10Mg- Selective Laser Melting (additive

manufacturing method, use of powered material)

- High strength, high hardness and dynamic strength

- Light weight

Property Value

Yield Stress 240 MPa

Young's Modulus 65 GPa

Hardness 120 HB

Tensile Strength 410 MPa

Elongation 5%

- TiAl6V4- High resistance to corrosion- Low specific gravity - Selective Laser Melting (additive manufacturing

method, use of powered material)- Great for motorsport applications

Property Value

Assembly Options

Benefits of Modular Eyelet

Node Design● Reduced Number of components

● Less Materials = Reduction in weight

● Reduction in weakness points (less thin members)

● Modularisation means less print patterns

● Easier assembly

● Looks slick

Extensions of Modular Eyelet

Node Design

● Locking teeth between surfaces

● Securing end-cap positions with locking pins

● Addition of a design for irregularly angled joints

● Hollow out solid material within stress / strain limits

● Determine best method for securing frame rods

within end-caps

What’s Next?

● Stress strain Testing

● Investigate concept extensions

● Investigate material options and printing techniques

● Incorporate into frame design file and test rigidity

● Iterate
