Acoustic Analysis
Noise is increasingly the subject of new regulations for the protection of human health and safety as well as for improving the environment in general. As well as sound levels, the perceived sound quality of products from washing machines to vehicles is often an important part of the customer buying decision so must be considered during product development. m+p Analyzer for noise and vibration measurement and analysis provides a full range of capability for these applications. Real-time fractional octave filters satisfy all acoustic applications from simple sound pressure, sound power for equipment legislative requirements, intensity mapping to isolate sources to sound quality metrics for product refinement.

Strain Measurements and Experimental Stress Analysis
Experimental structural testing using strain gauges is necessary in a wide range of applications from airframes and sub-assemblies down to individual components such as turbine blades, satellites, wind turbines, buildings, bridges and many others. These tests enable the engineers to compare the acquired data with the predicted results from the design calculations.

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.

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.

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

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.

Rotating Machinery Analysis
The Rotate software package is part of the m+p Analyzer Software for noise & vibration measurements and analysis. It provides a wide range of data acquisition and analysis tools for capturing and understanding noise and vibration induced in rotating and reciprocating machines by their motion. Fixed and variable speed machines are accommodated as are both structural vibration and condition monitoring diagnostics. Multiple tacho inputs can be processed for accurate speed tracking during analysis. Spectral mapping, order tracking, time history and orbit data analysis are all available.

product
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.

Time Domain Replication (Road Load Simulation)
The powerful graphical editor makes it easy to review and compile your field sample data for use in the test lab. The point editor, filters, velocity and displacement compensation ensure the test feasibility is evaluated at an early stage. The continuous closed-loop controller then replicates the test files with very high levels of precision. The control algorithms use a continuous coherence averaging technique to ensure a stable proactive control loop that will not only provide accurate replication but will also respond to changes in test item dynamics.
