Vehicle Specifications

In January 2013, three third year mechanical engineering students started the University of Toronto Baja SAE team. The focus of this team would be to develop engineering design skills through the design and fabrication of a one passenger off-road vehicle. Over the past 14 months, the team has completed its goal, building a functional vehicle that is prepared to compete in the Baja SAE competition in May 22 at Pittsburg, Kansas.

For the first several months, the team worked on the conceptual design of the vehicle, defin-ing the principal design parameters of each subassembly of the vehicle. From this process, several off the shelf components for the drivetrain, suspension and brakes were purchased. Also, the team prepared for upcoming recruitment event for new members in September.

In early October, the design of the chassis was finalized in CAD and a prototype of the chassis was constructed. The prototype process gave an opportunity to refine the design the chassis by being able to physically see if our design parameters were correct, or over/under de-signed. In addition, it allowed new team members a way to understand the design decisions that were cho-sen for the design of the chassis

Once the prototyping phase was completed, the fabrication of the chassis commenced. From late November to late February, countless hours were spent cutting, bending and welding steel tubes and machining mounting brackets for several sub assemblies.

This Year in Review ContinuedThrough this fabrication process, sev-eral opportunities were given to new team members to design and fabri-cate their own components. In par-ticular, the brake and throttle pedals, steering column mounting, drivetrain and brake system mounting were fully designed and built by new team members. This allowed them the op-portunity to develop their design skills through a hands-on application.

Upon the completion of the chassis, the engine from Briggs and Stratton arrived. This initi-ated the assembly of the drivetrain assembly onto the chassis. In addition, from this point, several other sub assemblies were fully assembled and mounted to the chassis.

At this current point, the car has been fully assembled with all of the necessary components. The vehicle was tested and tuned on May 6 and 11 to ensure its optimal performance. In addition, the final full assembly of the vehicle will be shown in an unveiling event in May 15.

The entire project and club would have not been possible without the support from the MIE department at the University of Toronto. We are very grateful for their help to get the club started and their continuous support in the development of our club. In addition, we would like to thank Ryan and Keith from the MC-78 Machine Shop for their help and suggestions on the fabrication of the vehicle.

Finalized Baja Vehicle During Testing

For next year, the team has the following improvements planned:- Design and Implement Compact Custom Made Final Drive- Iterate and Optimize Frame to Decrease Weight and Wheelbase- Implement Rear Semi Trail Arm Suspension- Implement Cutting Brakes to Improve Cornering- Implement Data Acquisition Systems to have Seemless Recording of Test Data
