1. Multi-Screen Option for Vibration Control and Data Recording | ||||||
|
With the increasing popularity of multi-output PC workstation graphics
cards and the increasing demand for remote monitoring of ongoing Vibration
Control tests, m+p international have introduced the impressive new Multi-Screen
option to both the The Multi-Screen option allows the display of multiple online graphic windows on multiple display monitors using the same system PC workstation and/or a remote PC workstation with or without multiple monitors attached. On the local PC workstation that performs the Vibration Control test, using a multiple output graphics card, up to eight monitors can display a total of eight online graphics programs, each displaying up to 16 windows, including up to 4 spectra/time pulses per window. All of this total up to 64 spectra per online display program, including PSD, linear spectra, transfer functions between any set of test channels. In total, eight monitors allow for online real time display of up to 512 spectra, all user-definable, with the possibility to store/load pre-defined layouts per online display program. Of course, for many users this may not seem that important as 512 channels is well above their normal operating parameters. However, it works well with just 4 channels, each one with a full screen display, improving clarity and allowing the user to get an instant picture of what is going on with greater ease. |

m+p international have extended their services to include on-site or
return-to-bench system calibration. For more information please contact

3. Time Domain Recording during Vibration Control | ||||||
|
m+p international have recently won orders for a total of 144 channels of real-time vibration control and dynamic data recording systems from the European space company EADS Astrium. Satellite shock and vibration testing is a complex and expensive undertaking and often requires high-channel counts for control and monitoring during the testing. Also because tests can only be run once to avoid overstressing the system, it has been the practice to run two separate systems, one for control and another for data acquisition; tape recorders have also often been used for this in the past. Running two systems means double the channel count to connect up, two operators and difficulty synchronising the two - all factors that mean that recording is not always done hence increasing the risk of loosing valuable data. m+p international's solution is based on their VibControl family of software and the latest VXI Technology front-ends that have combined both advanced control and real-time throughput data capture into one system. Both functions operate in parallel with data recording operating seamlessly in the background. Only one set of sensor channels needs to be instrumented hence saving time and greatly simplifying the set-up and operation. The recorded time sample data can be post-processed to refine the real-time frequency analysis produced during the test or can be analysed directly in the time domain using the m+p SmartOffice software suite to do transient and cross-channel event correlation, e.g. to determine event sequences that led to failure. Because recording the data to disc does not affect real-time control
performance this also means that raw time sample data recording can be
a routine operation thus providing that extra security backup and improved
feedback on all tests without the added costs. The VibControl system is
capable of all vibration test modes and the front-end has up to 102 kS/s
sampling frequency per channel with direct recording to SCSI disc drives
and has 24 bit ADC resolution with 130 dB dynamic range. |

4. Dynamic Strain Gage Measurement | ||||||
|
We recently completed a new project for a Naval Research Centre, in the
area of Dynamic Strain Gage Measurement. Used for the shock testing of
new frigates, the system can record multiple channels as throughput files
to the host PC's hard disk, for higher channel counts a local throughput
disk is also supported. Utilising VXI Technology's data acquisition cards
and our SmartOffice Analysis suite we have put together a neat solution
for anyone in this area of acquisition.
