vibration table test

vibration table test

(OP)
Hi,
how would You simulate vibration test (random+fatigue) of following model:
box structure made of closed profiles with inside tray running on steel wheels on two profiles.
This trolley is prevented from motions in three directions but of course there are clearances in each direction around 1-2 mm. Therefore this trolley can vibrate separately from box. How can I connect it with box for frequency response  analysis? Can I include contact in Ansys in frf analysis?

Best regards,
G
