Hi everybody.
I am thinking about modelling Percussive rock drill to estimate and decrease the sound which is obtained during the work. I appreciate if anyone has an idea. and about the difficulty doing that in COMSOL.
i am looking forward to hearing from you
kind regards,
alan

Hi
then I would start to ask myself what is generating the noise ? the rock or the drill device ? and how are they related, then identify the physics needed to analyse that further, and finally to check with what is available in COSMOL.

Good luck

hi
the idea is that the various parameters that are suspected to influence sound varied in order to propose appropriate future measurements on the drill steel to improve or validate the model. Some material from previous studies are available. And possibly a smaller sample could be performed.
The model could be performed by solving diffekvationer or FEM and BEM and FEM with analytical assumption of radiation from ythastigheten it could also be designed using the SEA analysis with specially written boundary conditions. The latter procedures may not come to describe the radiation of different geometries as well as FEM and BEM, but it could be used to increase understanding of the boundary condition.
best regards
