How do the number of trials affect the conversion of an SRS into the Time
Domain for Response Simulation Function Tools (NX 10)? What does the damping
ratio represent and how does it relate to Q?
Solution
The conversion of an SRS into the time domain is an iterative process where
values are tried until they reasonably fit the original SRS. That's where the
number of trials comes in. The number of times it iterates is controlled by
the number of trials.
The damping ratio represents the critical damping ratio for a single degree of
freedom resonator. The critical damping ratio is equal to 1/(2Q). A Q of 10 is
eqivalent to a critical damping ratio of .05 (5%).
