#### Next Meeting
### Meeting report 2 : 23/02/2011
#### General administration

Meeting lead: Yehan Tang
Secretary: Jan Bleumers
Meeting start: 14u Meeting end: 16u
* hours: 2u

##### Present

Hongzhu Qian, Yehan Tang, Zhengyuan Huang, Haowen sun, Jan Bleumers, Willem Noyen, Yared Reda

#### Agenda

1. Update from coach about the 4 delivered documents 2. New team member 3. Discuss general concept of the car 4. Case SSV part 1 5. Case Simulink

#### Discussed topics

1. Plan of Approach, Cooperation contract, WBS and Gantt are approved, only the actual making of the car and spent hours had to be adjusted. This has been done.
2. Yared Reda joined the team today, his info had been entered in the Cooperation Contract.
3. The car will have 3 wheels, 2 on the front axle, which will be the driving axle, and 1 on the rear. Questions about steering, cvt and material choice remain open.
4. For Case SSV part 1 we have to make a Sankey Diagram and calculate the best gear ratio by hand.
5. For case Simulink we have to simulate the SSV in the race and make a graph of different gear ratio’s against race time.

#### Action list

| Task | Responsable | End date |
| Case SSV part 1 – Sankey diagram | Jan / Willem | 08/03/2011 |
| Case SSV part 1 – calculate gear ratio | Yihan / Yared / Hongzhu | 08/03/2011 |
| Simulink – simulate race to find ideal transmission ratio | Haowen / ZhengYuan | 08/03/2011 |

#### Next Meeting

08/03/2011 after seminar and coach meeting

### Meeting report 3 : 8/03/2011
#### General administration

Meeting lead: Yehan Tang
Secretary: Jan Bleumers
Meeting start: 14：30u Meeting end: 16u
* hours: 1.5u

##### Present

Hongzhu Qian, Yehan Tang, Zhengyuan Huang, Haowen sun, Jan Bleumers, Yared Reda

##### Absent

Willem Noyen (medical reasons)

#### 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.

#### Action list

| Case SSV part 1 – Sankey diagram | Jan / Willem | 08/03/2011 |
| Case SSV part 1 – calculate gear ratio | Yihan / Yared / Hongzhu | 08/03/2011 |
| Simulink – simulate race to find ideal transmission ratio | Haowen / ZhengYuan | 08/03/2011 |

#### Next Meeting

15/03/2011 after coach meeting

### Meeting report 4 : 15/03/2011
#### General administration
##### Present

Hongzhu Qian, Yehan Tang, Zhengyuan Huang, Haowen sun, Jan Bleumers, Yared Reda, Willem Noyen

#### 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.
