Modeling thin air layer between vibrating solids

Dear forum users! I model vibroacoustics of a solid structure, consisting of several parts, in a frequency domain (Solid mechanics module). The structure itself is in the air. Some parts are very close to each other, but don't contact to each other. How can I set boundary conditions at the boundary of these parts (instead of fully modeling the pressure acoustics in the air gap between them) to take into account action of only normal vibrations of one solid on the other and the absence of tangential forces of one solid on the other? Thank you!

You may have to look into analytical models for this https://ris.utwente.nl/ws/portalfiles/portal/6075267/t000000b.pdf
