Objective

The objective of the Senior Design Project for Team 10 in the 2010-2011 academic year is to develop a successful hydraulic regenerative braking system to implement onto a 1988 Columbia Par Car golf car. Integration of the regenerative braking system will require a transfer case mechanism to be designed, analyzed, built, and installed. If the team finds a transfer case then it will be selected and installed.

Scope

Within this project, our team will present a mechanically driven golf cart that includes hydraulic regenerative braking. The design and analysis will be conducted on all non original parts. The team will also need to write and program the digital controller that will control the transfer case and hydraulic valves with feedback from the pressure transducers and sensors.

Deliverables

A list of deliverables are to be delivered to the client by May 4th, 2011:

• A fully functional golf cart with hydraulic regenerative braking that adheres to the appropriate safety standards
• Supporting Documentation which appropriately memorializes the team's efforts
• Three-dimensional models and two-dimensional drawings of all non-standard parts.
• Design verification of the mechanical and hydraulic systems.
• Design verification of supporting brackets.
• Provide a cost analysis on a projected volume of 500 units/yr.
