Study Notes
Introduction to Kyburz PLUS II
- The PLUS II is a single-person electric vehicle designed for elderly people and those without driver's licenses.
- It has a maximum speed of 10, 20, or 30 km/h.
- The range is between 65 km and 120 km.
- The vehicle weighs 300 kg and has a maximum payload of 160 kg.
CAD Model of the PLUS II: Exploded View
- The PLUS II has an exploded view that shows its various components like the chassis, bodywork, windshield, electronics, door, steering system, and front wheels.
Drivetrain
- The drivetrain is featured with an exploded view, emphasizing its role as a key component.
3D Solid Models I: Boolean Set Operations
- Boolean operations allow combining or modifying solid primitives using union, difference, and intersection.
3D Solid Models I: Different Modeling Steps
- A single simple part can be represented through different modeling sequences.
3D Solid Models II: Boundary Representation Model (B-rep)
- The B-rep model uses topology, including faces, edges, and vertices, with corresponding geometric data like surfaces, lines/curves, and points.
Parametric Modeling
- Parametric modeling allows for creating models that can be easily changed and updated.
- Parametric models are created by linking geometric entities using parametric relationships.
- They are created and manipulated through user interaction with the CAD interface, spreadsheets, or tables, and by implementing constraints and dimensions.
Basic Sketch Geometry
- Sketches should be kept simple, with complex 3D modeling features added later.
- The process involves defining a shape, extruding it, rounding edges, and optionally mirroring it.
Reference Sketch Plane Selection
- Any datum plane or planar face can be used as a sketch basis.
Sketch Positioning
- Aligning sketches with the global coordinate system is crucial.
- Symmetry should be considered, with examples provided like creating a flange, adding holes, mirroring, and creating a pipe.
Modeling Operations – Based on one profile or “sketch”
- Various modeling operations can be done based on sketches, such as extruding, revolving, and sweeping.
Extrusion
- Extruding a profile creates a 3D object by extending it along a specified direction.
Patterns
- Rotating a sketch around a vertical axis creates a 3D object.
Sweeping
- Sweeping a profile along a defined path or curve creates a 3D object.
- Examples include variable pitch springs using three helixes and a profile.
Example: Wheel hub from the PLUS II
- The wheel hub is the connector between the wheel and the drive shaft and the brake.
- It includes components like the wheel hub itself, the drum brake, the brake backplate, the bearing, and the axle shaft.
