Progress is going as planned!

We have passed the starting line of the construction of the car a long time ago now.  , we started with the frame of the car. Since some parts of the car have arrived, it is easier to visualize the car even without the body of the car. The electro group has made progress with the schematics. The programming group is working hard on a can-buss and interface. Soon we will also pass some milestones but let us first elaborate on what we have accomplished so far. 

At the beginning of the year we started with the welding the frame of the car, which with the help from Lindholmens Tekniska Gymnasium (LTG) is almost finished. A huge thanks to the students Rikard, Nils and Johan for their participation. The collaboration with LTG made it possible for us to get the frame finished on time.  The students are qualified welders and with their great expertise, the frame is going to be as stable as possible! 

A few important parts for the car have arrived. The seat is now complete with a seat belt and a helmet for the drivers maximum safety. We now have brakes, a gas pedal and the steering wheel is under construction. Another part of significance is the wheel suspension. The wheel suspension has passed all necessary tests and the construction of it has started. You can see the wheel suspensions progress in the picture below.

The electro group and programming group has also continued their work. According to Bridgestone World Solar Challenge rule set we need to document every part of the car which includes the electrical parts and the circuits. As the electrical circuits are planned and the battery box is on its way, they now have a lot of documentation to do. After a certified engineer has approved the documents, it needs to be send in for inspection so that Bridgestone World Solar Challenge knows that the car is safe to drive. Parallel with the electro group the programmers have started to develop a CAN-BUSS. They have also worked hard on the interface of the display. The display is going to be placed close to the steering wheel, so the driver can see for example, the speed of the car. Their work continues with more documentation and development. 

With the frame almost finished, the parts coming in, a finished interface and the documentation going smoothly, we are right were we want to be. Although we still have a lot of work ahead of us. Milestones and deadlines are coming at us at the speed of light and we are excited to see the car. 

Car reveal

As you may have noticed on our social media, the construction of the car has finally begun. This means that our main focus of the development process in the CAD programs are coming to an end. Unfortunately we can not show you any of the parts constructed in CAD because they are confidential at this time. As time goes by, our energy focuses on simulations of the aerodynamic body. After months of designing and calculating. We are hereby revealing that the car is going to look like following:

On this design we have performed aerodynamic calculations on the air resistance. It is important to minimize the power consumption of the car throughout the competition for best result possible. Right now we have the right necessity's to cross the finish line. Since a good placing in the competition is important for us, we continue to improve our model. This is of paramount importance because of air resistance. This stands for almost 85% of the total power consumption. 

Below, you can see two pictures that show the contour plotting and the vector plotting of the absolute pressure of the car.

WHAT HAPPENED IN FALL 2018?

We have made great progress with the solar car during the fall. The mechanics and aerodynamics team have been working really hard on the car's chassis. To develop the concept of the car so the construction can begin as fast as possible, but still in a thoroughly way to make sure that the vehicle will take us across the finishing line in Adelaide. We have also teamed up with a local profession school to weld the body of the car, which now is in progress. With the concept of the car ready the electro subgroup could start calculate the power needed to get the car running and compere it with the amount our solar panels can absorb. 


After a inspiring visit to Jönköping solar team we have reevaluated how we are going to develop some parts of the car, for example the programming team has re-planned what information about the car the driver is supposed to see and are now working on these changes. The visit also reminded us of that the competition is getting closer and closer. As a result of that, the logistics subgroup started working on a cooperation with the other Swedish solar teams to get the car shipped to Australia since we all participate in the Bridgestone World Solar Challenge. 


The new year started with a two day project management workshop led by Mats Nyman from our gold sponsor Wenell, to which we are very thankful. We are now confident that we have what it takes to participate in Bridgestone World Solar Challenge and really looking forward to show you what we are working on and show the progress of the cars construction. Lets go to Australia!
