Snad tam nejsou žádné další chyby, do tisku to jde ráno a doufám, že se to
stihne.

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.
