Spring Break Part I

Hi There,

It’s been a while since we’ve updated you. It’s spring break here at Dartmouth but DFR is not taking a break, in fact we’re just gearing up! We’ve been doing lots of work fabricating our designs and changing them along the way of course. We just submitted our last 3 big forms to Formula Hybrid last night so we’re off to the races! Here are a few photos from our days to give you an idea of what we’ve been up to:

This was at about 4AM after we finished prepping the chassis for some final welds! Team Leaders unite

This was driving the chassis to Maine to be welded by our friend Aaron who works for Soleras LTD.

At Aaron’s house we tack welded the battery box but soon found that the mig torch was not so good in all the tight corners we have. image3

Thanks Marden’s for this great hanging chair! New addition to the lab and absolutely crucialimage4

We made the engine mounts and the engine is now sitting in the chassis without straps!image5

More welding pic’s at Aaron’s house. This is one of our battery cages.image6

Lastly a nice picture of our seat belt position! image7

That’s all for now! In the days to come we will have made the electric powertrain mounts and finished our welding!

Full Control Pipeline

We’ve got it! We’ve got a full control pipeline! Data comes up from the vehicle components like the engine to our controller and we are able to control the motor based on that data! This is a huge deal for it means we have hybrid control in our vehicle working and we can’t wait to test it in the car. What we have running in this video is a very simple linear control algorithm for testing purposes that demands a speed from the motor. In the car we will demand a torque from it instead of speed and have a much more complex state machine enabled so that the car is better optimized for the endurance event and has shut down procedures.

On another note Alex and Khet made some rear suspension tabs today so we will hopefully have that done by March 11th and start rolling things along. Pictures to come.
