Meeting rules

   We will have at least have one meeting per week. All team members are required to be on time for these meetings and to

have prepared all agreed topics/actions. All decisions will be reached with consent of all member, all members are thus

required to give input on all topics/ideas. There is no time limit on the duration of a meeting.
   The team secretary is responsible for creating and distributing the meeting report to all team members within 2 days after

the meeting took place. Each team member then has the chance to reply to this to comment on the contents of the report. These

comments will be incorporated in the report by the secretary. At the start of the following meeting, the final report has to

be approved by the whole team.
   At the end of each meeting an action list will be drafted and each item will become a team member’s responsibility. This

list will be updated and discussed in the following meeting.

Wiki rules

   The team secretary updates the blog and wiki page at least once a week.
   The wiki page will contain the most recent action list.

Absences

   Everybody should attend every activity of the team (and be on time). If someone is not present, that person should inform

 the team leader of the reason.  If someone is late, he/she has to buy the rest of the team a drink.

Sanctions

   When we encounter troubles or problems and have a difference of opinion, we will vote to get the best solution. In this

 process, we avoid unnecessary fights with each other.  

Communication with the coach

   We will collect all the problems and pose them to our coach during the next class.

The plan of approach

Client

   The client in this project is the Umicore Solar Team. 

Contractor

   The contractor is Illumination, a fictious company founded as a requirement for this project. It consists out of the students of group 12 of

 the Engineering Experience 4 course at GroupT. The company ‘employees’ are: 

 Teamleader:		Yehan Tang

 Secretary:		Jan Bleumers

 Team members:	Haowen Sun, Hongzhu Qian, Zhengyuan Huang, Yehan Tang, Jan Bleumers

Project description

   The purpose of this project is to develop a miniature, toy version of the Umicore Solar Team’s solar car. This toy car must run on solar

 power without the use of batteries, it’s behaviour has to be predicted and compared with the actual Umicar (on an energetic level) and has    to

 take part in a race.

   To aid us in the development, a number of seminars will be given at GroupT, consisting out of a general presentation of the project

 description, a presentation given by the Umicore solar team, a presentation by Fablab about the possibilities of their workshop, a seminar  on

   Simulink and a seminar on technical drawing.

Approach of the project

   The project is split into 3 chapters: Engineering, Enterprising and educating. The total budget for the whole project is € 200, a solar 

 panel and a DC motor.

   In the engineering part of  this project we will design a small solar car that will operate solely on solar power. We will design and build a

 chassis, gear train and electronics, and will use solar panel and DC motor which GroupT borrowed us for the purpose of this project. We will

 also simulate the race to calculate the ideal transmission ratio and perform a freeroll simulation using Simulink (this data will be compared

 to the results of a real life test held in week 9). The drive shaft of the SSV will be analysed, and 4 Sankey diagrams will be composed: 1 

 estimated diagram early in the project, 1 after the freeroll test and 2 for the actual umicar. We will create a 2D technical drawing of the  SSV

 frame.

   In the enterprising chapter of the project we will perform market research to identify competitors, design a complete business plan,

 potentially rename and re-logo our company, create a web page and engrave the logo on the SSV.

   To manage the budget, a cleartable of expenditures will be kept, accompanied by proofs of payment.

   In the educating chapter we will create a ‘report of solutions’, containing the calculations and solutions to the engineering and

 enterprising questions/problems. We will also write an ‘online process report’ containing all documents made in the analysis and orienting 

 phase, the story behind the design and creation of the SSV (like a blog), a temporary and final description of the design, and a final  process

 report.

Deadlines:

   By the end of week 1 we will present a Cooperation contract, plan of approach, WBS and Gantt chart. In case of ‘no go’ we will present an

 amended copy of the required documents at the end of week 2.

   At the end of week 6 we will deliver the ‘Case SSV part 1’, Simulink and fill out PA 1.

   Depending on the weather conditions, we will test the SSV in week 9.

   Somewhere in the course of week 9 through 14 we will race the SSV (depending on weather conditions).

   In week 11 we will hand in ‘Case SSV part 2’ and fill out PA 2.

Project limitations:

   The SSV will only be able to drive forwards, not backwards.

   There will be no steering installed as the race is held on a straight track with a guidance rail.

Expected result

   We expect to build a functioning SSV (within the specifications of the client) which is capable of completing and possibly winning the final

 race.

Agenda

1. Progress on “Case SSV part 1” 2. SSV transmission

Discussed topics

1. Due to to many unknowns, the sankey diagram, gear ratio and Simulink have not yet been completed. We received some good info from our coach concerning these topics and will continue working on them.

2. After realizing the difficulty of creating a CVT (continuously variable transmission), we decided to go for a normal gearing system (gears) and to try to lower friction and losses as much as possible.

Agenda

1. Progress on “Case SSV part 1” 2. SSV transmission 3. Solar panel mounting 4. Chassis 5. Process Report

Discussed topics

1. We received more info concerning the 3 big parts of the Case SSV part 1 from our coach.

2. We decided to buy our gearbox as making the gears ourselves is too hard. A home-made gearbox will also be less efficient as an expert-made one. If the precise ratio can not be bought we will buy one close to it and adjust the wheel diameter to correct.

3. We will mount the panel with the aid of 3 or 4 telescopic antennas, that way the panel is adjustable in every direction.

4. For the chassis we will use a plate of plexi-glass cut in the appropriate shape. We will discuss how thick the plate should be and what the shape is going to be.

5. Everyone has to write their part of the process report and send it to Yehan. Jan will then join all parts together and check spelling+grammar.
