Project Overview:

•  A paddle-shift control system designed to hypothetically work with a future UVic Formula SAE car.

•  Modeled Project Components: –  Currently used FSAE Steering Wheel –  Primary System Housing –  Paddle Shifters and Brackets (2 Types) –  Internal Mechanisms (Pin, springs, sensors, etc…)

•  Project modeling done in SolidWorks, FEA analysis done in COMSOL MultiPhysics 4, rendering done in Keyshot 2.1

Learning Objectives:

•  Editing in Assembly Mode •  Design for Manufacturing / Final

Assembly •  Generating Complex Shapes •  Photorealistic Rendering •  CAD Modeling of Real Objects •  FEA for Design Verification

Editing in Assembly:

•  Choose driving dimensions in a way that facilitates later modification.

•  Editing in assembly mode allows the designer to see how parts interconnect, expediting design evaluation and modification.

Design for Manufacturing:

•  CAD enables the designer to better visualize the part, helping them envision the manufacturing process.

•  CAD enables visualization of final production assembly stages.

•  All electronics are commercially available components.

Complex Shapes:

•  Featured on steering wheel and carbon fiber version paddles.

•  Steering wheel grip: –  Lofted cross section

and filleted revolves.

•  Carbon fiber paddles: –  Lofted boss – sketched

“ribs” and an outer guide curve.

Photorealistic Rendering:

•  Very high detail models •  Rendered with KeyShot

2.1 •  Key technologies:

–  Fast ray-tracer –  HDRI image based

lighting –  Realistic material shaders

and camera effects •  Not capable of

significant animation

KeyShot  2  

Modeling of Real-World Objects:

•  Steering wheel and splined shaft are CAD models of existing parts.

•  Created to verify paddle shifter dimensions and design.

•  Sketch images greatly aided the fast and accurate creation of these part models.

FEA for Verification:

•  COMSOL Multiphysics 4.0 with LiveLink for SolidWorks

•  Used primarily for design verification rather than optimization.

•  Maximum expected usage loads were applied to the paddle brackets and the primary system housing.

Issues Encountered:

•  Initial design proved sub-optimal. Evaluation of mass properties in SolidWorks revealed a very heavy part and initiated a clean sheet redesign.

•  Minor problems importing models to KeyShot for rendering (required us to use the STEP file format).
