Zdravím,
až to dotvoříte (je to dobré), tak mi to zašlete, ve čtvrtek jdu k 
děkanovi žádat o peníze,tak si to vytisknu a předám.
Díky, Vita Hli.

>> About The Team
>>
>> Formula SAE is a student design competition which originated in the 
>> U.S. in 1981. Since 1998 the competition known as Formula Student has 
>> begun in Europe. The goal of the competitors is to design and develop 
>> a formula car. The final evaluation also takes into account the 
>> costing and manufacturing technology problems including the carbon 
>> dioxide footprint of the whole design. All these parameters has to be 
>> considered by the student team playing a role of a fictive company 
>> which develops and sells this final product. The car has to be 
>> inexpensive, reliable and easily maintanable in order to succeed at 
>> the competitive market. The target customer is an unprofessional 
>> weekend autocross or sprint racer. The production plan is to meet a 
>> demand of 1000 units per year.
>> The time spent by students on this project is about 35 000 hours 
>> every year.
>>
>>
>> FSE0.1 Prototype
>>
>> The spatial tubular frame is made from the structural steel. Its 
>> welding was performed using MAG method and the final frame was 
>> reinforced using honeycomb aluminium panels.
>>
>>
>> Frame
>>
>> The first generation car FSE.01 designed by CTU CarTech Electric Team 
>> is based on hybrid chassis which are made both from S235 tubular 
>> steel and EN AW 6082 aluminium alloy water cut panels. The main space 
>> frame is welded using MAG technology and subsequently reinforced 
>> using aluminium honeycomb panels glued into the frame. The rear part 
>> of the chassis made from the aluminium alloy is welded using TIG 
>> technology and bolted to the main space frame. This hybrid chassis, 
>> where the aluminium honeycomb panel is used as a main firewall 
>> component, provides a very safe cockpit for the driver. For the best 
>> driver's protection a 6-point safety belt is used. The car's bonnet 
>> is manufactured from the glass fibre composite.
>>
>>
>> Suspension
>>
>> Both axles are using independent and adjustable suspension system in 
>> order to provide an appropriate dynamic and handling car 
>> characteristics. The axles are equipped by a push-rod suspension 
>> type. The forces acting on the suspension are transmitted into the 
>> custom made shock absorbers via rocker arms. In order to increase and 
>> control the axle stiffness anti-roll bars are installed on both 
>> axles. The design of the whole chassis was subjected to the FEM 
>> analysis in order to ensure the required fatigue life.
>>
>>
>> Brakes & steering
>>
>> FSE.01 brake system uses two independent hydraulic circuits equipped 
>> with adjustable biasing. The front wheels are provided by disc brakes 
>> mounted on the front uprights. Willwood GP320 front brake calipers 
>> are coupled with brake discs having an effective diameter of 223.4 
>> mm. The rear disc brakes are mounted to the frame in order to reduce 
>> the rear unsprung mass. AP
>> Racing CP4227 rear brake calipers act on the brake disc equipped with 
>> an effective diameter of 194 mm.
>>
>> Above the driver's legs there is a mechanical steering system which 
>> includes RSK Trade cross cart steering rack with the ratio 90 mm 
>> displacement of the rack/ 360deg of steering wheel rotation. 
>> Steering wheel, which is made from glass fibre composite, includes 
>> electronic features showing the required data to the driver.
>>
>>
>> Battery Pack
>>
>> We can proudly state that the energy needed for the propulsion of the 
>> vehicle is stored an accumulator pack of our design. This battery 
>> pack contains Li-Pol accumulator cells with an electrical capacity 40 
>> Ah per each cell. The total number of the cells is 54 and the 
>> energy stored in the whole accumulator pack is as high as 8 kWh. The 
>> accumulators can be disconnected from the inverter by AIR contactors 
>> at any time. Two AIR contactors were used in order to fulfill the FSE 
>> rules. These two contactors can operate in case of both high voltage 
>> and high current event. All accumulator cells real-time monitored by 
>> the battery management system which is also used for the accumulator 
>> pack cooling management. The accumulator pack can be always 
>> disconnected manually at any circumstances.
>>
>>
>> Cell Distribution Scheme
>>
>> The accumulator pack contains six accumulator units (stacks) 
>> containing less than 5 MJ energy each. These stacks are connected in 
>> series. In every stack there are 9 accumulator cells in total. Each 
>> cell is equipped by a temperature sensor providing the increased 
>> safety of the whole accumulator pack. The container of every stack is 
>> manufactured from a self-extinguishing material in order to ensure 
>> desired degree of safety.
>>
>>
>> Mounting and safety
>>
>> The accumulator pack frame is a TIG welded aluminium structure. This 
>> design provides the required structural rigidity and the desired 
>> accumulator cells protection. This frame is mounted to the steel 
>> chassis of the car.
>>
>> The weight of the final accumulator pack is 84 kg. The mounting of 
>> the accumulator pack has to withstand forces generated by a 20 
>> g deceleration such that the accumulator container does not enter the 
>> driver's cockpit area and therefore this loading path is crucial for 
>> the safety of the driver. The mounting has to be able to bear a 
>> loading generated by a deceleration of 10 g in all other directions.
>>
>>
>>
>> Tak jsem to udělal až po battery pack. Zabralo mi to něco málo přes 
>> hodinu, ten zbytek už dneska do půlnoci nestihnu, tak aspoň máme 
>> něco. Možná těch informací tam je pak dál až moc. Musí to taky trochu 
>> vypadat tak aby se to lidem chtělo číst, kdyby se to zkrátilo a dalo 
>> větší písmo tak si myslim, že by to neuškodilo.
