Abstract [en]

This final thesis is carried out at BAE Systems Hägglunds in Örnsköldsvik. The mission was to construct and integrate a new semi-active damping unit in the terrain vehicle BvS10. Questions that came up during the process, among others, was how to mount the damping unit to the vehicle in a flexible way without exposing it to unnecessary wears.

A generation of the concept is made in 3D using CATIA V5 of a possible solution to the problem. The idea is to weld the unit to the skid girder which is one of the main constructions of the track system. In this way the damping unit will come closer to the track system, which will partly protect it from impacts from below and minimize current problems with breaking forces in the torsion shafts.

The complete construction was then analyzed, first by theoretical calculations and then with the FEM-tools in CATIA V5. The result of this analysis showed that the construction had a good potential to resist deformation and high tensions. Drawings in 2D of the assemblies were then generated for the left and right damping units separately.
