Shock Control
Shock testing simulates an extreme event that a unit under test is exposed to during handling, shipment, explosive event and/or daily use (e.g. dropping an object). The profile for this type of testing is defined by the shape of the time domain waveform together with its amplitude and duration. The m+p VibControl vibration control system offers full functionality for classical shock and shock response spectrum testing as well as for tests using external pulses or the capture of transient signals.

Mixed Mode Testing
The Mixed Mode add-on modules for the Random Vibration Control Software allow tests to run with sine tones and/or narrowband random signals superimposed on a random background. Mixed mode testing is a complex control task, and m+p VibControl supports three modes: Sine-on-Random (SoR), Random-on-Random (RoR) and Sine-on-Random-on-Random (SoRoR). Gunfire burst control can also be superimposed in each case.

Data Reduction
Data reduction systems with or without time history recording to throughput disc are frequently used in critical aerospace testing applications where complete measurements of a high number of channels are required for post-test and possible failure analysis. The m+p VibControl data reduction system configurations are tailored to the specific needs of high-performance measurement applications requiring hundreds or thousands of input channels.

Random Vibration Control
Random control is one of the two basic and most common excitation modes for Environmental Shaker testing. Random performs real-time closed-loop control of PSD profiles. The m+p VibControl vibration control system allows the user to designate all input channels as control, watchdog and/or measurement channels.

Vibration Monitoring
Vibration tests must be safe and reliable and this is especially true for high value specimens in critical aerospace testing applications. Here, m+p Coda offers maximum safety: The monitoring system captures and records data such as acceleration, temperature and strain continuously during vibration tests - irrespective of the vibration control system in use. Each channel can be configured separately for total flexibility.

Transducer Calibration
m+p SensCal
Regular transducer calibration is an essential requirement for maintaining the accuracy, reliability and repeatability of the results obtained from a measurement system. m+p international’s m+p SensCal program provides a quick and simple process for calibrating accelerometers (piezo-electric with charge output or IEPE, piezo-resistive, capacitive) in your laboratory, as well as velocity or displacement transducers.

Time History Recording to Throughput Disc
For the most critical tests time history data can be recorded in parallel with vibration control with no reduction in control performance. The real-time throughput data capture function of the m+p VibControl system allows you to record all selected channels continuously in the time domain on the embedded data server (“throughput to disc”) irrespective of the channel count and the frequency range utilized. This means that you can always access all the original data for analysis purposes.

Impact Testing
The Impact Testing software of the m+p Analyzer real time analyzer includes useful tools like the selection of a roving hammer or transducer, selection of data points/nodes, double impact detection and rejection, definition of force and exponential window and a user-definable display configuration as a visual measurement feedback.

Dynamic Signal Acquisition and Analysis
m+p Analyzer systems are available for field and laboratory use from 4 to many hundreds of measurement channels. From gathering simple time history data to narrowband (FFT) spectra, fractional octaves, wavelets, shock response spectra and much more, m+p Analyzer real time analyzers can be used with a wide range of instrumentation hardware including our own m+p VibPilot, m+p VibRunner and m+p VibMobile systems, National Instruments (CompactDAQ USB, PCI, PXI) and VTI Instruments (PCI). Low cost portable instruments to systems for distributed measurements can be configured for maximum flexibility. Measurement data from all sources are stored in a common format so it is easy to compare and handle results from any measurement source.

Condition Monitoring
m+p Coda is a versatile monitoring system that captures and records signals coming from sensors such as accelerometers, thermocouples, strain gauges, and pressure transducers. Limit checking and alarm monitoring is provided for every active channel. The active channels are clearly displayed in a separate window, out-of-limit data can be seen at a glance. Alarm events are entered into a log file and can be reviewed at any time. You have the option to change the alarm limits online at any time without stopping the data acquisition.

Environmental Vibration Testing
Whether for independent monitoring or just adding additional channels to an existing vibration controller, the m+p Analyzer real time analyzer provides an ideal solution for measuring vibration and other responses during a shaker test or with shock machines. All test modes allow in-parallel throughput to disk recording so that the raw sample data is available for post-test analysis.
