Rules 2018

 

 

Participants

 

The competition is open to students from further education institutions. Registration is to be posted or e-mailed to Project and Competition Leader by the 15th of January 2018. We have 2 competition classes. One for tertiary colleges, one for universities. A maximum of 15 teams will be permitted into the competition on a first come first served basis. The closing date for applications is 15th January 2018. An additional two exceptional “wildcard” entrants may be accepted by the competition organisers

 

 

 

Participation fee

 

The fee is 2000 SEK per team. The fee will be invoiced along with confirmation of acceptance document. Payment should be received within 30 days for the registration to remain valid. Teams withdrawing from the competition before 31st January 2018 will receive a full refund.

 

 

 

Prize

 

First prize in each class is 5000SEK. In addition to this the team which uses the least amount of energy in both classes and wins the competition will receive an additional 5000SEK. Every university team that beats the competition record from previous years will receive a 2000SEK bonus. The current competition record is 0,73Wh/pkm (Eximus 2, Dalarna University 2017). Every tertiary college that beats the competition record from previous years for tertiary colleges will receive a 2000SEK bonus. The current competition record is 1,26Wh/pkm (Bromangymnasiet 2015).

 

 

 

Team leader

 

Each team should have a team name and a specific team leader (teacher or student) who is responsible for communication with the organisers. Institutions can register more than one team if desired.

 

 

 

Crew and use of vehicle

 

Each crew is dedicated to only one vehicle. Each team must have their own unique vehicle.

 

 

 

The competition

 

The aim of the competition is to run a vehicle 3,36 km using as little energy as possible. Energy is measured and expressed in terms of Wh per person per km. In order to calculate each team's final score energy consumed is divided by the number of passengers on the vehicle.

Each vehicle will be escorted by an official on a draisine (railway bicycle).

 

 

 

Record Conditions

 

In order for a new record to be approved the average tail wind speed for the completed journey must be less than 2,0 m/s. Any teams that use less energy than the existing record will receive a bonus of 2000kr irrespective of the tail wind speed. Should a record be set out of the competition hours the record will stand but will not be considered in the competition result.

Any team which the competition organisers believe have a chance of breaking the record will be afforded a second run in order to attempt to achieve this  after the official competition is concluded.

 

 

 

The track

 

The track is a railway with a regular Swedish track width, nominally 1435 mm. There are some slight variations in the track width. Level road crossings, curves, slight declines and inclines as well as a set of points do occur. The whole distance is to be navigated at one time without derailing or any of the onboard team touching the ground.

 

Track Profile

Free Room

 

The rail construction standard allows for a “small space“ on the inside of each rail for steering. See Swedish rail regulation  BVF 586.20. for details. Frequent usage of bicycle trolleys  has even worn a couple of millimetres ”free room” on the outside of each track.

Vehicles

 

The vehicle must have a braking system and be constructed in such a manner as to avoid derailing. All competing passengers must be able to sit in a normal sitting position with their buttocks resting on a horizontal surface with a back support. The back support should be at an angle between 60 and 90 degrees and be at least 35cm high.

 

 

The approved angle for the back support is displayed as the green area on the diagram.

 

 

Each vehicle must have a either a solid or a net floor to prevent limbs being caught on the track. Wheels should have a protective cover to prevent injury to the crew when the vehicle is in motion.

 

The vehicle is to be powered by an electrical power source with a voltage between 6 and 48 V and an maximal instantaneous power consumption of 20A. Reuse of energy created by breaking is allowed which means only the net energy use is measured. Braking energy should be fed though the measuring apparatus to the battery supply.

 

After the registration fee has been paid each team will receive a weather proof box which will be used to house the measuring instruments on the competition day. This will sit between the batteries and drive system. This box should be incorporated into the vehicles design. The box contains a fuse and connectors to attach to the measuring apparatus. The dimensions of the box are ca 40 cm x 30 cm x 20 cm. The box has a lid which can be opened in order to install the measuring apparatus

 

 

 

The construction must be deemed to be safe, i.e. no personal injury is likely to be the result of heavy breaking, malfunction, accident or derailing. The competition organisers may disqualify vehicles which don’t meet sacfety requirements. To avoid uncertainty the organisers can help, upon request, and inspect vehicles prior to the competition.

 

 

 

Driver and passengers

 

Each vehicle may be crewed by a minimum of one and a maximum of 6 persons. In the event of a 6 crew vehicle being used the minimum weight of the fully clothed and equipped crew should be 300 kilograms. For a 5 person crew the minimum weight is 250 kilograms, 4 person crew is 200 kilograms, 3 person crew is 150 kilograms, 2 person crew is 100 kilograms and a 1 person crew is 50 kilograms. Weight is controlled prior to start.

If the weight of the crew is less that the minimum weight permitted then addition weight will be added to the vehicle to achieve the necessary minimum weight. The driver must be sober and unaffected by drugs.

 

The possibility exists to "borrow" passengers for each vehicle should the competing team wish to lower the weight of the vehicle. These passengers will be local school children who see the event as a fun and interesting thing. However all motion and breaking functions on the vehicle must be operated by a team member.

 

 

 

Tävlingsåket

 

Fordonet startar från stillastående och ska under tävlingen hålla en genomsnittlig hastighet av mellan 10 -15 km/h. Besättningen får inte vidröra marken eller spåren under körning. Fordonet ska stanna och stå helt stilla inom 20 meter från mållinjen.

 

 

 

Test driving of the vehicles before the competition is compulsory

 

Before the start of the competition each team will test drive their vehicle over the complete course. Each vehicle must be able to complete the course under its own power with no 3rd party assistance. All teams are welcome to test drive their vehicles from 08.00 Thursday 24th May until one hour before the competition starts on Saturday 26th May.

 

Teams can borrow weights from the organisers to simulate crew members if desired.

 

The track crosses a road used by motor vehicles. Discuss with the organisers before your test drive in order to ensure safety.

 

 

 

It is forbidden for teams to use the competition track before 24th May 2018

 

To allow all teams an equal chance in the competition, irrespective of their location to the competition track, practicing on the actual 3,34 km competition track is strictly forbidden before the 24th May 2018.  Other sections of Dellenbanan can be used for practicing throughout the year.

 

 

 

Testing the points system

 

Competitors may want to familiarise themselves with the railway points system. A points junction exists at the west end of Delsbo station which can be used for testing

 

 

 

Advice!

 

A stable and well thought through rail guiding is necessary to avoid derailing. Note that three wheeled vehicles with a flange only on the inside of each rail can derail easily as the track width varies. Three wheeled bicycle trolleys usually have a thin steering flange on both the inner and the outer edge of the rail. As the competition track is part of a real railway there are many  things to take into consideration. Teams will meet derail-guards, foliage, gravel, electrical connectors, rail-bolts, level crossings etc. which may become hinders to wrongly constructed vehicles.

 

To avoid derailing we recommend strongly that competing vehicles are tested on a railway in plenty of time before the competition. Closed industry tracks with points and level crossings are useful for this purpose.

 

 

 

Railway Points

 

Along the track there is a set of points that has to be navigated. The vehicle must travel straight forward through the points along the “undivided” right hand rail.  This means that the vehicles’ wheel must be constructed so as not to derail as it passes the openings in the left rail.
