Abstract [sv]

Detta examensarbete är en del av fyra i förstudien till projektet Bromsvagn. Projektet Bromsvagn är tänkt att skapa en testutrustning i form av ett släpfordon. Vars yttersta uppgift är att testa långvariga belastningar av fordon i full drift. I detta examensarbete konstrueras axlar och upphängning på konceptnivå. Konstruktionen sker i programmet CATIA V5 utifrån de av BAE Systems Hägglunds AB givna förutsättningarna för tillverkning.Vissa komponenter kommer förbrukas under vagnens livslängd, till dessa kopplas relevanta underleverantörer av standardkomponenter. På utvalda modellerade delar kommer hållfasthet beräknas via handberäkningar och FEM-analyser i denna del av CATIA V5. Vid modelleringsarbetet tas hänsyn till påverkan av två parallella examensarbeten i samma projekt. Dessa två examensarbeten behandlar konstruktionen av chassit och utformningen av hydraulsystemet.Slutsatsen är att denna konstruktion har potentialen till att klara den tänkta upp uppgiften. Beräkningarna konstaterar att de modellerade delarna kommer klara sina teoretiska krafter utan större problem. Dock rekommenderas vissa fortsatta beräkningar i framtida projekt.

Abstract [en]

This degree project is one part of four in the preliminary study of the Bromsvagn project. The Bromsvagn project is intended to create a testing equipment in the form of a trailer. Our ultimate task is to test long-lasting loads of vehicles in full operation. In this thesis the design of axels and suspension will take place at the concept level. The construction takes place in the program CATIA V5, based on the manufacturing conditions provided by BAE Systems Hägglunds AB. Some components will be consumed during the life of the trailer, to which relevant subcontractors of standard components will be linked. On selected parts of the model, strength will be calculated by hand calculations and FEM-analyzes in this part of the CATIA V5 program. The modeling work considers the influence of two parallel examinations in the same project. These two degree projects deals with the design of the chassis and the design of the hydraulic system. The conclusion is that this design has the potential to cope with the intended task. The calculations indicate that the modeled parts will manage their theoretical powers without major problems. However, some calculations are recommended in future projects.
