The Chassis and Internal Structures onboarding task is intended to familiarise members with basic Solidworks Weldments commands while developing skills to design parts with considerations in mind. The Onboarding is divided into 3 parts:

  1. Chair

  2. Rollcage Design

  3. Full Chassis Design (Optional)

Once members complete the required tasks, they can be assigned and move on to working on different structures projects within the team.

Feel free to contact any of the leads when you get stuck! But… do try to figure out a solution by yourself - a huge part of learning SW is about playing around and finding out!

Part 1 : Chair

To familiarize you with Solidworks, recreate the following Chair using Solidwork Weldments:

If you are unfamiliar with weldments, refer to the following page for the Weldments 101 session and extra resources:

Part 2 : Roll Cage Creation

Apply what you learn and design around some constraints! Create a roll cage using SolidWorks Weldments and the model of the driver included here:

Driver File Below

Recommended: It is always good to separate different objects as 2 separate parts when working in CAD! Try to start a new assembly, insert the provided part and create a new part for the rollcage. Try to figure out how to work with two parts in a single assembly with in-context sketches. This is a little hard to feel free to reach out if you are stuck! (although working in a single part is also fine in this task)

(When exporting an assembly file for review, go to files → pack and go → export as a zip file)

 

Constraints:

  • Must have hoop at the front and rear of the driver’s head

  • Cage must have 50 mm offset from the driver’s head 

  • Deflection guards at the front of the roll cage to protect the driver from sides 

  • Use the 4 given points in the file as mounting points for the roll cage

Once you are done, you are welcome to tackle the tasks we present during our weekly checkins!

Part 3: Full Chassis

For those who want to challenge yourself and prepare for more challenging chassis tasks, design a mock chassis!

Possible constraints:

  • Dimensions of driver (CAD model above)

  • Suspension mounting points

  • Wheelbase/track (distance between wheels)

  • Battery box location

  • Overall chassis dimensions

  • What else can you think of?

Honestly, it doesn’t even have to be a chassis for a solar car! If you can design chassis for a go-kart, a formula SAE, a baja SAE car, …a f1 car…? go for it! Show us you have the skills!
