Construction of tilt table for Clear River Racing : A mechanical device run by electrical winch (English)
Abstract [sv]

Clear River Racing på Karlstads universitet har varit i behov av en demonterbar tiltbänk i syfte att kunna utföra ”tilttestet” på deras racerbil. Tilttestet är ett av flera event som racerbilarna testas på i de årliga tävlingarna som anordnas av Formula Student. I denna rapport har målet varit att framställa en CAD-modell av en demonterbar tiltbänk som drivs av en elvinsch. Framtagningsprocessen började med tre potentiella koncept som utvärderades med hjälp av en besluts- och elimineringsmatris. Det resulterade i att det bäst lämpade konceptet fortsatte för vidareutveckling. Materialval utfördes på axlarna i anordningen genom användning av CES EduPack och glidlager valdes ut efter undersökning. Låglegerat stål valdes som material till axlarna. Resterande delar av anordningen konstruerades med ett konstruktionsstål, som har benämningen S355J2H. Beräkningar gjordes dels för hand och genom FEM-analys i programmet Creo Simulate 5.0.

Resultatet blev en tiltbänk som är kapabel till att motstå de potentiella belastningar som förekommer under testet med 5 som säkerhetsfaktor. Modellen är uppdelad i 17 olika demonterbara delar exklusive elvinschen och sammanlagt blev vikten på anordningen 490 kg. Den tyngsta demonterbara delen vägde 53 kg. CAD-modellen gjordes i programmet Creo Parametric 5.0.

Abstract [en]

Clear River Racing at Karlstad University has been in need of a demountable tilt table in purpose of performing the ”tilt test” on their racing car. The tilt test is one of many events the cars are tested on at the annual events organised by Formula Student. In this report, the goal has been to produce a CAD model of a demountable tilt table driven by an electric winch. The production process started with three potential concepts, which were then evaluated with the assistance of a decision and elimination matrix. This resulted in further development of the best suitable concept. Material selection was performed for the device’s shafts using CES EduPack and plain bearings were chosen after research. Low alloy steel was chosen as material for the shafts. The remaining parts of the tilt table were constructed with a construction steel, labeled S355J2H. Calculations were made by hand a by FEM-analysis with the computer program Creo Simulate 5.0.

The result was a tilt table capable of withstanding the potential loadings which will occur during the test, with 5 as a factor of safety. The model is made up of 17 different demountable parts, excluding the electric winch. The totalt weight of the device was 490 kg and the heaviest single demountable part weighed 53 kg. The CAD model was made with the computer program Creo Parametric 5.0.
