Finally, a check of the eigen-frequencies of
all parts of the machine was done to avoid
any risk of resonance.
Conclusion
Thanks to EnginSoft’s expertise in dynamic
simulation it was possible to obtain an
accurate simulation of a huge planetary
stranding machine in a short time.
The results of these simulations support
Mario Frigerio’s mechanical designers for
the dimensioning of the machine. On this
large machine no mistake is acceptable.
Virtualisation allows saving time in the
development process and is an alternative
to the classical approach, in particular
when historical data, from similar
applications, is not available.
This collaboration between companies
made it possible to optimise the design
of this challenging project and preserve
the high quality level and performance of
Mario Frigerio’s products. n
