I need to design a vibration table (approx. 1000mx1000mm) to test products between 7-200Hz.
I was wondering if it is recommended to make the table structure from standardised, extruded aluminum profiles bolted together to reduce the cost (material + time) or does one have to go with a welded structure?
Yes, I am aware of the results of the Junker vibration test with regards to bolted connections and it seems like a bad idea because all the fasteners would loosen. However, maybe there is a workaround to use these aluminum profiles?
I sincerely appreciate any advice and/or previous experiences with these.
