Inclusion of product mass in dynamic analysis
Inclusion of product mass in dynamic analysis
(OP)
I have crusher support steel that I am designing for dynamic loads and to avoid resonance. Do I need to include the mass of the product in crusher and chutes when calculating frequencies and vibrations? My thinking is no because it is not attached to the system.

I've dealt with a similar situation in designing libraries. Should the books be part of the seismic weight? Some say no; I say yes. In a long duration, Mexico City style earthquake, I imagine the books falling off the shelves and lying in a big heap that most likely moves along with the floor system as a result of friction.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

If your structure is supporting your mass at any time, at the very least, you have a case where the product mass matters.
