Reaction Vibration Forces
Reaction Vibration Forces
(OP)
We are multi-discipline manufacturing company of chiller and pump packages. We typically do not do foundation design – we just provide reaction table (dead, live, wind, snow and earthquake load) for our packages. Customer on our last project is asking us to provide reaction vibration forces. Any idea how to accomplish this would be greatly appreciated.






RE: Reaction Vibration Forces
In the industrial structures industry I work in, one of the biggest gripes we get from clients is excessive vibration of a foundation or structure from a piece of rotating or reciprocating equipment.
It's rare that we get this data, but you could alleviate some of the heat from your company when the client complains about vibration by providing the following to the foundation engineer: operating frequencies, mass, center of mass, center of rotating mass, 3-axis phase angles of the vibrations, and accurately dimensioned bolt hole size and spacing.
As a Value-Added item, you could sell the option of vibration isolators mounted to your machines. The data above is still required, but also include the damping of your isolators.
