Analytical models for temperature prediction on welding (2008)

Formula-Bio started out as a dream of building a race car with only three students\nand thereby showing the world that everything is possible if you put your passion\ninto it. In this internship report the story of Formula-Bio and the reasoning behind\nthe FB01 can be found. A large part of the report is about the modifications it took\nto make the FB01 to be the car that is was supposed to be; a robust, lightweight car\nthat could give the thrill of fast cornering while still being environmentally as clean\nas possible.\nAs you will find in the introduction it all started in July of 2007. At this point the\njourney of building a racing car with only three students began. The platform was\ngoing to be Formula-Bio, a self engineered racing category that has all the thrills of\na racing car but with an environmentally safe character. The basic restrictions were\nthat the car would run on a "green" fuel, would be as lightweight as possible and\nthat 95% of the people should fit into it. Bio-Ethanol was chosen for the fuel, hence\nthe marketing name Formula-Bio. The first car would be named the FB01.\nIn the following two years the members of the team worked long days and many\nhours to realize their dream. At the beginning of 2009 the car was presented as a\nrolling chassis with the engine fitted into it. After this the team worked for another\nhalf year to make the engine run and to make the car driveable.\nFinally in August of 2009 the first few hundred meters were clocked on the FB01.\nUnfortunately a few problems occurred and the team decided to first test the FB01\nand some loose parts of the FB01 in a test-environment.\nAt this point this internship started. The goal of the internship was to make the\ncar drivable and robust enough to race. First the suspension of the FB01 was tested\non failure. These results let a need of stiffening and improving some suspension\nparts. Furthermore, the plumbing of the cooling system and oil system had to be\nredesigned, produced and fitted into the car. Remaining tasks were to make a robust\nshifting mechanism, improve the human interface, install launch and traction\ncontrol, and build telemetry on the car to read out suspension and braking data.\nIn addition it was desired to re-calibrate the engine and shifting mechanism. Furthermore,\nto find out if the suspension is though enough and works well, a shaker\ntest should be performed during which the car will be excited over a specific frequencyrange\nat each wheel with interaction between the exciting of the wheels.\nDuring the internship the suspension parts were improved, the new cooling systems\nwere fitted into the car, and the new control systems together with telemetry\nwas designed and placed. Furthermore to make the robust shifting mechanism the\ncar was equipped with a throttle-by-wire system. The remaining tasks after the internship\nare, calibrating the new shifting mechanism and throttle-by-wire system,\nplacing the accelerometers, and preforming the shaker test. At the moment of writing\nthe calibration of some systems has began and are preformed at the roller test\nbench of KMS (Kok Motor Sports).
