Abstract [en]

This master thesis work where performed at Atlas Copco AB division SDE techniques in Örebro. SDE techniques designs and manufactures surface drilling equipment for a demanding worldwide market. The constant ambition to reduce the development cost and time demands new and improved dimensioning tools. ADAMS is a simulation software that can be used to find the dynamic loads on a vehicle early in the design phase. This thesis work is a start for a new method of dimensioning boomsystems and other machine parts for surface drill rigs. The surface drill rig was built in ADAMS with moment of inertia and mass from CAD models. The boomsystem hydraulics was modeled with a function describing the oil compressibility and the flexibility of the cylinder walls. The complete model was compared with measurements on a surface drill rig during tramming (propulsion of the rig). It was concluded that the model could not be verified with available measurement data. It is recommended that new measurements are done and a track model is developed in ADAMS. The parameters and constraints in the ADAMS model must be carefully recreated if a successful verification is to be possible.
