Bicycle Kit Design in SolidWorks

Introduction

• The lecture is about designing a simple bicycle kit in SolidWorks.
• Includes creating parts, assembling, and animating the bicycle model.

Part Design

1. Steering Handle

• Creating the Steering:

  • Use the top plane to sketch a symmetric line.
  • Define dimensions: 70mm, 40mm, 17.6mm, 45mm, 35mm from the origin.
  • Fillet: 6mm at two ends, change corners to 26mm and 8mm.
  • Extruded Boss: 20mm, set midplane.
  • Apply color: orange.

• Arc and Cut:

  • Sketch a half-circle using Center Point Arc.
  • Set point to coincide, define radius: 12.5mm, 11.1mm.
  • Offset 4mm, extrude cut both sides.

2. Handle Rod

• Designing the Rod:

  • Sketch circle on the backside: diameter 20mm.
  • Distance from outer edge: 15.82mm.
  • Extrude: 225mm.

• Plane Creation and Adjustment:

  • Right plane to create auxiliary plane at 20mm.
  • Edit sketch, adjust to 20mm.

3. Handle Extension

• Sketch Additional Handle:

  • Create line, convert to arc, define dimensions: 230mm, 30mm, 68mm radius.
  • Draw circles on front plane: 30mm diameter, extrude as needed.

• Mirror and Finalize:

  • Mirror handle using front plane.
  • Add color and appearance.

Assembly

Frame

• Frame Construction:
  • Use splines and ellipses to create the frame.
  • Define dimensions and use planes to build structure.
  • Ensure smooth connections and symmetry.

Wheels

• Wheel and Tire Design:
  • Sketch wheel profile, revolved boss/base.
  • Define tire threads and spokes using patterns.

Seat and Pedals

• Seat Construction:

  • Sketch seat shape using splines and multiple planes.
  • Mirror to ensure symmetry.

• Pedal Creation:

  • Sketch and extrude different parts of the pedal.

Final Assembly

• Assemble Components:

  • Use mates to align and connect parts, ensuring proper rotation and movement.
  • Add mechanical mates for chain and sprockets.

• Animation Setup:

  • Use motion manager to animate bicycle.
  • Adjust revolutions per minute (RPM) for realistic motion.

Conclusion

• Successfully designed and assembled a bicycle in SolidWorks.
• Highlights the importance of precise sketching and mating for functional assemblies.
• Encourages further exploration and practice in SolidWorks.
