motor mount, pizza, etc.

We've received the motor mount parts!

 The wiring harness for the engine has been modified. We've removed all unnecessary wires and shortened it to fit in the car cleanly.

 The rear uprights are coming together. The only parts missing are the bearing cups, which should be machined this week. That means we'll have a roller by the end of next week.

  All suspension mounts are done. Here are the fronts, along with some bearing cups for the uprights. It's coming along!

We can't forget about the shop pizza!

Impact Attenuator, Upright and Motor Mount Progress

 This week we made quite a bit of progress. 

 The mount for the AGNI 95r electric motor we're running is finished being designed. FYI for those of you who are interested in using this motor - the mechanical drawing is wrong on their website. Specifically, the bolt pattern is a 196mm diameter circle, instead of 194mm. The lever arm you see is a tension mechanism for the final drive.

Miles and I spent some time last Friday testing impact attenuator - or in Layman's terms, the bumper. Plascore was generous enough to sell us some attenuator material, which is made of 3003 aluminum honeycomb. It's great at absorbing energy at a constant force. We tested the material's strength against displacement in RPI's concrete testing Instron machine.

Here you can see the localized compression of the cells. 

 I was able to get some work done on the jig for the uprights tonight as well. 

Taylor and Joe cranked out a lot of parts this weekend! We've got to keep this momentum up if we're going to finish the car in 4 weeks like we plan to.

Until next time...
