SAE Car Show -- May 2nd

Stevens Formula SAE and Autism Speaks will be co-sponsoring a Car Show on May 2nd on the Stevens Campus. The team will be revealing the 2010 car at this event and would like to invite everyone to attend.

It's Starting to Come Together

The team has been hard at work in and out of the shop. On the car front we were able to get all of the suspension members mounted this week. We also received the front uprights from George Wohlrab, the schools machinist, which came out great and mounted right up. We also settled on a plastic for the body panels, PETG. This material is lightweight and easy to form and should make an excellent body. In addition to the work in the shop we have been finalizing our cost report. The cost report is a document which calculates the cost of manufacturing 1000 cars in one year. The team did very well on this report last competition and are looking to continue the good work. All in all it has been a very productive week with more assemblies being put on its beginning to look like a car. The next steps are to get the differential mounted, the axles cut and fitted, and get the new engine running.

The team has been hard at work making progress on every sub-assembly of the car. All of the rear engine mounts have been fabricated and fitted. We are working on designing and installing the front mounts, which will utilize the stock R6 mounting plates for easy installation and removal of the engine. The team also fabricated the mounts for the pedals and designed an adjustable seat for this years car. We also finalized the design for the body which will consist of three plastic body panel and a fiberglass nose. The plastic panels will be along the sides of the car and one over the front to act as a hood. The fiberglass nose will cover the impact attenuator. The picture below will give you an idea of where the plastic panels will be. With tons of work still to do on the car we are planning on working over spring break, next week, to get the car done in time. The goal for the coming week is to have all of the mounts for the different components installed and hopefully have a rolling chassis. We are also hard at work on the Cost Report another critical piece of the competition. The cost report is based on a production run of 1000 cars in one year. The team must cost all aspects of the car down to the installation of the nuts and blots. Last years team was able to place 15th in this event and with their help we hope to do just as well. We have a lot of work ahead of us, but are confident that this years car will be the most competitive in school history.

Suspension and Engine Progress

The team has made lots of progress since the last post. We have completed all of the suspension arms and are working on the frame mounts. Fabrication of the rear knuckles has also begun. They have been jigged and are in the process of finish welding. After the engine failure last week the team scrambled to find a new engine and in the process made contact with Bay Cycles in Bayonne. With help from them we have found a new R6 engine to put in our car. With this great news we are working on mocking up the engine mounts with our old engine, while awaiting the new one. We are at the point where all of the components we have designed are coming together and we are starting to see the fruits of our labor.

Action Deadline 1 Met

The team has successfully submitted the first round of Action Deadline material to the Formula SAE judges. This includes the Impact Attenuator Data, the Design Report, and the Design Spec Sheet. The major piece of this was the Impact Attenuator Report. For this the team had to design and build a device to limit the forces on the driver in the event of a front end collision. Our design was a box filled with aluminum honeycomb sheets. To test our design the team dropped a 417 kg weight from about 6 feet on the the attenuator. Data was collected and our design passed with flying colors, to see a video of the test click here.
