Our Project Goals for the Next Two Semesters
Frame:
The primary purpose the frame provides for the Baja vehicle is to protect the driver. Secondary purposes include supporting the engine, transmission, suspension, and other components. In order to fulfill these requirements, the frame must be strong, rigid, and able to withstand shocks associated with off-road impacts.
Previous year’s Senior Design team designed a frame for the vehicle to improve its performance. The team also conducted several FEA tests on the frame to determine whether or not the frame would fulfill these purposes. The job of the team this year is to construct the frame, and then to prove that the FEA analysis is valid. This will be done by static tests on the fully constructed frame, where a force is applied to the frame, and the resulting deflections are measured. From these deflections, we can determine strains and stresses, and determine whether the frame is safe to use.
In addition to this, the team must design and fabricate mounting points for the engine, transmission, suspension components, and other parts. These mounting points need to be fabricated and attached to the new frame so that the other vehicle systems will easily fit into the frame.
Improve suspension (coilovers, hopefully!!):
The suspension on the baja vehicle needs to allow the car to travel easily over off road terrain. The suspension used last year worked but it can be made better. The suspension used last year did not have a spring over the shock absorber, making the suspension subpar.
The design we have for the frame does not have any mounting points for the suspension, so there is a need to design the suspension so that we stay on or below the center of gravity.
Incorporate new transmission with high and low gears in drivetrain:
The drivetrain transmits power from the engine to the wheels. The drivetrain on last year’s vehicle was stressed to the point of failure, causing a poor performance in the endurance race. We must design and build the drivetrain to ensure that it is reliable enough to pass through the entire event at a high level of performance.
Decrease turning radius (if time allows)
Meet all safety requirements set by SAE:
71 pages of guidelines to follow, or we can't compete!Use other features such as steering, brakes, etc. similar to that of the previous vehicle:
They worked well before, so why not?!
Have everything combined so that the car functions well for competition at the end of spring semester:
Competition is in Portland, Oregon on May 16-19, 2012
2011 Team After Competition
Rock Crawl 2011
