4. Experimental Procedures for Operational Modal Analysis of a Power Pack on a Drill Rig
University essay from Linköpings universitet/Mekanik och hållfasthetsläraAbstract : All structures have modal properties such as natural frequencies and damping. In engineeringit is often of interest to estimate these modal properties for certain structures, to be used whenmodelling for example fatigue. This is done by computing them from finite element models, by using experimental measurements or both. READ MORE

5. Development of new rotation concept for rock drills
University essay from KTH/Maskinkonstruktion (Inst.)Abstract : In blast hole drilling, it is desirable to be able to drill as close as possible to the edge of the tunnel. The minimum distance from the edge is defined by the radial size of the rockdrill. Most of the rock drills used today have a rotation motor that rotates an axel parallel to the shank, which further rotates the shank through a gear set. READ MORE
