Overall Goal:

• To demonstrate that the preliminary design follows all system requirements and is feasible within resource, time, and manufacturing constraints

• To establish a foundation for moving forward with detailed design and prove that the design is ready to proceed

• By this time, all architectures are final. This review will discuss the architectures and design options that were considered and explain why the final architecture was chosen over the other options

• Preliminary CAD should exist. We should have a general understanding of how each part of the car will look.

  • This allows advisors to have physical context for the choices we are making

• System bounding boxes must be fixed after this point

• Major system-design critical OEM components should be selected and validated

Validation:

• Approach should be validated with proper hand-calcs and FEA

• A discussion of how you found your inputs will be required to convince the audience that your analysis is correct

• Explain why you used this methodology

Implementation Plan:

• At the end of PDR, why you chose the design and how you will implement it/proceed with it should be defined

  • General manufacturing process/steps selected

Between PDR and CDR, all that should change is the optimization of designs. Weight savings, improving intra-system interfaces and repairability, more in-depth planning for manufacturing
