Shaking up for noise and vibration
analysis
New approach to provide a completely integrated environment that can be used in a matter of minutes to acquire, analyse and report the most complex of data requirements
In the area of noise and vibration analysis, the last 20 years has seen extensive technology development However, the software has often been left behind in older Unix environments

That is, until SmartOffice.
Set-up is simple using the SmartOffice geometry wizard, multiple components of any type, point and click connection of nodes and direct node identification to each measurement step are included.
Measurements are taken using a modal hammer equipped with a force transducer at the tip.
Thus, during a hammer impact, the exact excitation force can be measured.
Based upon the hardness of the tip, different frequency ranges can be excited.
Accelerometers are used to measure the structural responses.
During the measurement step, auto-power, cross-power, FRF and coherence functions are calculated, automatic detection of double impacts and overloads is done, automatic node number increment and automatic data storage are performed.
This level of automation increases engineer productivity and reduces costs.
The final modal analysis is carried out using the combined time/frequency polyreference methods from the University of Cincinnati.
These algorithms have proven to be the most stable and flexible across a wide range of structures.
Using the advanced modal parameters estimation wizard, the resonant frequencies and damping values are calculated based upon the impulse response functions, a stabilisation diagram is calculated and the stable parameters selected.
In a second step all modal vectors are calculated using a frequency domain approach.
Once the animated geometry is created this can be exported to the final report document and sent to the customer who is able to manipulate the view using the SmartOffice animation toolkit within the Word document.
