ANALYSIS AND FATIGUE:
Modal Analysis of Structural Systems
Specifications for rotating equipment with substantial
dynamic loads often require that no structural modes occur in specified
frequency ranges. Dynamic analysis of complex floor systems is often
substantially complicated, and computer finite element methods are
Rotating equipment was a concern during the design
of tanks in an industrial process. These large tanks were to be
subject to substantial dynamic forces, and required significant
vacant space underneath for piping systems. Finite Element Analysis
was used to model a variety of support and restraint systems for
each of the tanks. The final system was designed to minimimize tank
movement, and to reduce fatigue in the system.
HGC Engineering has assisted mechanical engineers
on numerous occasions when developing support or restraint systems
for equipment or machinery with substantial dynamic loads. A complicated
support structure was required for a packaged refrigeration system,
designed to minimize vibration impact on both the equipment and
on the supporting roof structure.
