Notch at a Calculation
Use an equation to limit the drive signal in Random test mode. The software compares the equation to the limit and then adjusts the drive to keep the calculation lower than the limit.
In the case of force limiting, the user can sum the output of several force transducers and notch on the total force applied to the structure.
New VR10500 Configurations
The VR10500 now supports eight and twelve-channel configuration options (previously increments of 16 only). The configurations are as follows: 8, 12, 16, 20, 24, 28, and 32. After 32 channels, the channel count increases by increments of 16. The VR9500 is still the best option for four-channel-count systems.
Specify Weighting on Multi-Channel Control
Engineers can choose the algorithm the software uses to combine multiple control channels in Sine test mode. New to VibrationVIEW is the option to weigh the average of the selected channels.
The weighted average of selected channels allows the user to assign different weights to each channel. The software uses the weights to calculate the weighted mean values of all the control channels.
Add Control Channels Without Averaging
VibrationVIEW can multiply control channels using their average value in Random test mode. In version 2021.1, the software can calculate the sum of selected channels without averaging.
This feature is particularly beneficial when using a triaxial accelerometer, which measures vibration in three linear directions. The sum of the selected channels will display the overall acceleration from all directions.
Resonance Table Report Parameter
The new [ResTable] report parameter displays the peak resonances on a PSD graph in Random test mode. The user can select the channel(s) that will be evaluated for resonance peaks or set the measurement to automatic for all channels.
Additional Report Parameters
In addition to the Random [ResTable] parameter, version 2021.1 includes report parameters for maximum profile AVD values in Sine:
Additionally, the user can add Trigger Channels to an SRS report. A skewness parameter to meet standard IEC 60068-2-64 (2008+A1:2019) has also been added.
