This document summarizes a student project to design an electric bicycle using CATIA software and 3D printing. It introduces electric bicycles and their advantages over traditional bicycles. The document then provides an overview of CATIA, a 3D CAD software, describing its key capabilities and user interface. It explains how CATIA can be used to create 3D part and assembly models, apply constraints between parts, and integrate design with other applications like finite element analysis. The project aims to leverage CATIA to design an electric bicycle and 3D printing to prototype the design.

3. INTRODUCTION
• Electric bicycle also known as E-bike is a modification of conventional bicycle which
uses electric motor to replace the pedaling system.
• It reduces the human effort along with increasing the efficiency.
• It reduces the uses of motor bikes which reduces the pollution as it is eco-friendly
vehicle.
• It is available in affordable cost.

4. INTRODUCTION

5. ADVANTAGES
• Reduces human effort and increase the efficiency of riding.
• Beneficial in hilly and mountainous region.
• Eco-friendly transportation system.
• Helps in conserving petroleum.
• Even solar panel can be used for recharging the battery.

8. Developed by Dassault Systems.
Basically used for surface modeling.
Drafting to analysis feature.
Incorporates CAD, CAM, CAE, and other applications.
CATIA v5 is a native Windows application.
User friendly icon based graphical user interface.
Based on Variation/ Parametric technology.
Encourages design flexibility and design reuse.
Supports Knowledge Based Design.

9. CATIA V5 PHILOSOPHY
 A Flexible Modelling environment
 Ability to easily modify models, and implement design changes
 Support for data sharing, and data reuse
Knowledge enabled
 Capture of design constraints, and design intent as well as final model geometry
 Management of non-geometric as well as geometric design information
The 3D Part is the Master Model
 Drawings, Assemblies and Analyses are associative to the 3D parts. If the part design changes, the
downstream models with change too.

12. The Part Design application is used to create solid models of parts
Solid parts are usually created from 2D profiles that are extruded or
revolved to form a base feature
The Part Design task is tightly integrated with a 2D sketching tool
A library of features is provided to allow user to add additional details
to a base part
Parts can be modified by selecting their features in the specification
tree
Parts are stored in files with the extension .CATPart

13. The Assembly Design application allows you to create a product
model from a number of separate parts.
The parts in a product assembly are not joined together, but
assembled as they would be in a physical assembly.
The product assembly structure is hierarchical and allows you to
model complex product relationships.
Constraints can be applied between the parts in assembly to define
relationships between them

14. 1. Create a new CAT Product using File -> New ->
Product.
2. Use the Product Structure tools to lay out the main
assembly structure
3. Use Insert Existing Component or Insert New
Part to create geometry in the Assembly
4. Use Constraints to capture the design relationships
between the various parts in the assembly
