The thesis is an investigation of the Auto Tuning Vibration Absorber (ATVA) developed by Swerea IVF. Main focus is to improve the absorber so it becomes active for more frequencies and thereby get a more stable behavior and also to adapt it for different systems. Here the focus is on three systems; a pneumatic breaker, a test rig and a reciprocating saw. The investigation is made mainly by performing simulations in MATLAB, but also experiments on the test
