DESCRIPTION
WE ASSUME NO LIABILITY FOR ANY SAFETY ISSUES OR DESIGN FLAWS!
--> STILL IN PROGRESS !!!!
This Project includes the engineering documents of a three wheeled sigle seated electric lightweight L5e-A vehicle.
The vehicle is designed to be build with "simple" Tools and machines in an individual production or very small batches.
All documents in this product are accessible with open source or freeware Software.
Used Software:
- LibreOffice
- Free CAD
+ FEM Workbench
+ CFD OpenFoam Workbench
- Z88 Arion (topology optimization, Freeware)
- KiCAD
- Gimp
- Arduino IDE
- CooCox
To make the descissions in this project as transparent as possible, all big engineering descissions are evaluated with the following criteria:
- efficency
- simplicity
- safety
