Sammanfattning
The study, conducted in collaboration with Metalock Engineering, investigates the vibrations
characteristics of the Mirage MM1000i mobile machine, with the objective of a better
understanding of machine vibrations, identifying critical components causing vibration and
proposing design modifications to mitigate these vibrations.
The analysis combines physical vibrations measurements and Finite Element (FE)
simulations to discern the natural frequencies of the machine. A comparison of these analyses
enabled the localization of components where machine vibrations showed the strongest
resonance, which contributes to the understanding of the relation between critical components
with machine vibrations. The results highlight the swing arm and counterweight arm as
crucial components for vibration minimization. Based on these findings were concept
solutions developed, which primarily involved structural modifications of these components
to increase their stiffness and reduce their mass, leading to reduced machine vibrations. This
study lays the groundwork for a new machine concept with a lower risk of vibration and
chatter, potentially enhancing productivity.
