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

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