Bygelstolpar : Kraft- och spänningsanalys av bygelstolpar tillhörande Bruks mobila hugg 805 CT

This report is the result of a thesis as been implemented during the spring term 2009 at the University of Gävle. The company Bruks produces mobile chippers which are used for chipping logging slash, roundwood and parts of trees. The chipper is powered by a separate diesel engine and the chipper can be assembled on trucks, trailers or some other carrier vehicles. When the chip has passed the chipper drum, the chip is collected in an integrated bin which is mounted on the vehicles frame with dumping yokes. When these dumping yokes were designed they were probably created with large material dimensions. The aim with the degree project is hence to study the strengths of materials and, if possible, to suggest an arrangement that can decrease the total weight on the dumping yoke on Bruks´ mobile chippers 805 CT. The CAD-program Pro/ENGINEER was used during the project for outlining the 2Ddrawings, as distributed of constructors on Bruks, to solid 3D-parts. The three-dimensional assembly from Pro/ENGINEER was transferred to Pro/MECHANICA. The construction is complex and contains many components, and therefore the model has been divided into two different parts, the external and the internal dumping yoke. The conclusion of the degree project is that the product generally is not over dimensioned. However there are many options for optimizing, mainly on the external dumping yokes.
