Week 19: Turning in control
Week nineteen has been a week wherein we have presented our team on MDD-Day in Den Bosch, started with testing hardware interfaces, and assembled the inner-wheels and spring-damper systems on the DUT12.
One of these tested hardware interfaces is the motor controllers with the motors. We test this interface by making the motors drive exterior from the car, to prevent problems after their placement. Furthermore, it is very important to test the functioning of the two motor controllers as they are placed together in one carbon housing; instead of the conventional aluminium housing. Replacement and integration of two housings results in a weight reduction of eight kilo’s on a total of four motor controllers.
Also concerning the hardware domain; we started making a third version of the Electric Control Unit (ECU). The second version of the ECU did withstand most software tests, but due to our design some ECU connections where wrong side out, also one extra connection had to be added. Happily, V-PS and NXP too want to have the reliability of the DUT12 as best as possible, and support us in realising a third version of the ECU.
On Wednesday, Team Manager Max and Chassis Engineer Reinier, gave a presentation at Model Driven Development (MDD) -Day in the Brabanthallen in Den Bosch. Max told the audience about the content of one year DUT Racing and Reinier presented a deep dive topic about his half year internship at ALE, designing our monocoque as our team’s Finite Element Analysis specialist.
At the end of week nineteen we can say that we are in a far stadium of assembling most of the mechanical parts to the DUT12. So week 20 will be even more focussed on the parts that categorize the DUT12, as electrical driven!
