Datasheet

Acquire and Analyze Vibrations in Three Dimensions

Models to simulate structural vibrations must be validated using reliable experimental data.

Three dimensional scanning laser vibrometry is a unique tool for test and simulation engineers

to be able to quickly and very accurately determine operating deflection shapes and eigen

modes of complex objects across a wide range of frequencies. Measurement data are reliable

if they reflect the actual vibration characteristics of the real object. This is precisely what the

non-contact method guarantees. The PSV-500-3D Scanning Vibrometer was developed to meet

your needs in performance, accuracy and data analysis for both structural dynamics testing and

ultrasonic evaluations.

PSV-500-3D Scanning Vibrometer

Non-contact, Optical MeasurementAt the heart of every Polytec PSV-500-3D system is the laser Doppler vibrometer – a precision optical transducer for determining vibration velocity and displacement at a fixed point. The technology is based on the Doppler effect; sensing the frequency shift of back scattered light from a moving surface. By using three laser vibrometers incident on the probed sur-face from different angles resolve the x, y and z components of vibration. Apart from giving you the greatest precision, this process offers the security of a measurement method based on physical constants with minimal calibration requirements.

Your Benefits■ Non-contact – measure the true vibration of your

structure

In Focus: Time-to-marketThe 3-D Laser Vibrometer Advantage

Automate your Test Results: RoboVib®

The RoboVib® Structural Test Station combines two cost-effective technolo-gies: the PSV-500-3D Scanning Vibro-meter and a high precision industrial robot. RoboVib® allows a particularly high level of testing efficiency through integration into the CAE workflow, auto-mation of repeated tests, minimization of costs and time per test, and an overall increase in capacity utilization of the test lab resources. The test sequence is initially set out in the robot program based on FE geometry data. Then you can really get going: position the object, align the coordinate system, start the measurement – RoboVib® will automa-tically work throughout the entire test process. If desired, it will scan overnight, freeing up the test lab for new tasks the next day.More Info: www.polytec.com/robovib

Cost-effective and Seamless Integration into the CAE WorldCombining fast measurements with pro-cess automation, 3-D laser vibrometry can reduce the time and personnel needed for structural analysis. Up to 90% time savings can be achieved because it is no longer necessary to mount traditional sensors. The open system architecture simplifies data exchange processes, such as when exchanging geometries and measurement values.

High Density of Points, High Frequencies – Precise Model ComparisonScanning Vibrometry allows a virtually unlimited number of measurement points and thus a dense grid – a parti cular advantage for model comparison, where higher order modes can also be used as reference.

Accurate LocalizationAlthough 3 laser beams are being operated simultaneously, high pre-cision scanners and VideoTriangu-

lation work to achieve a laser footprint in the μm range. The CoherenceOptimizer

laser frequency control guarantees cross-talk -free measurement up to 10 m/s velo city over the full bandwidth. High frequency modes can therefore also be clearly resolved in ultrasonic devices. For macroscopic objects, the small footprint is a benefit near edges.

Ergonomic and SafeWorking with a PSV is always safe. Thereis no need for a dedicated lab or lasersafety specialist. A mobile system cabinetwith integrated swivel monitor providesstorage for all parts and accessories.Designed according ISO ergonomicstandards, relaxed working conditions are guaranteed.

Stay on Top of ThingsYou see what you get with the new built-in EagleView HD cam-era. Pin sharp images document your setup. Elaborate, low-noise 50° x 40° WideScan scanner tech-

nology allows larger objects or bigger areas of their surface to be captured in one scan. PSV is truly a full-field prob-ing technology allowing scan fields from mm2 up to m2.

Highly Integrated Fully DigitalThe PSV-500-3D Front-End design integrates the latest digital decoding and data acqui-sition 2) in one compact box. VibroLink transfers all measure-

ment data without conversion losses to the Data Management System. Unparal-leled low noise is the benefit.

Coping with GeometryThe integrated Geometry Scan Unit allows users to generate a three-dimen-sional point grid of the test object. 3-D shapes are probed quickly and reliably using the QuickSnap laser autofocus. Alternatively a 3-D grid can be imported from an existing FE model. Coordinate systems and nodal point definitions are maintained during the whole process. No matter what method is chosen: PSV always works with a consistent data model for geometry and resulting vibra-tion vectors. Angular sensor orientation errors are not an issue.

3-D Animation

Interactive Setup User-friendly drawing tools help you de fine the shape, orientation and point den sity of the grid on the video image of the object. Absolute geometry can either be read in from CAE/FEM files or can be measured directly on the object under investigation using the Geometry Scan Unit. The preferences for band-width, frequency resolution, vibration

excitation and channels are simply de-fined in a dialog. The PSV only requires one setup for all measurement points. Settings that have been saved from pre-vious measurements can be loaded by a simple mouse click from the project browser. The signal generator controlled by the PSV software ensures precisely defined vibration excitation.

Quick ScanThe laser beam automatically scans the whole grid and makes a vibration mea -s urement at each of the predefined points. While doing so, the laser is always opti-mally focused; the signal-to-noise ratio is permanently monitored and optimized. During the scan, the time responses and frequency spectra of the vibrometer and reference signals are displayed.

In the case of broadband excitation, the PSV-500-3D records the complete spec-trum for every measurement point and all deflection shapes of the measurement surface.

The FastScan mode enables deflection shapes to be determined in the shortest possible time (hundreds of measurement points in a few seconds).

*As an option/with optional accessories

Perfect VisualizationThe PSV software package provides an informative animation of the vibrations measured. The deflection shapes can be color-coded as 2-D or 3-D graphics for display purposes. Frequencies of interest can be easily selected from the spectra using a cursor. The video image itself can be animated in 3-D to show exaggerated, life like motion of the structure. Animated profile slices also help you to understand

the vibration in detail. Response to tran-sient events can be shown in high resolu-tion slow motion by using time domain animation*. For every individual meas-u re ment point, the per tinent spectra, trans mission func tions, coherence and time signals* are avail able for analysis. The graphics and animations can be easily used in impressive reports and presentations.

Flexible AnalysisThe Polytec signal processor is a high performance analysis tool similar to a spreadsheet, which makes numerous math ematical and statistical operations available for individual pieces of data or whole data sets. Data from other sensors can be simply imported and

linked to the vibrometer data. Using standardized export filters or the Polytec-FileAccess open interface, external soft-ware packages or your company’s inter-nal software can access the measurement data for modal analysis, sound field or power flow calculations.
