VIC VIBRATION HIGH-SPEED

Vic-3D High-Speed Vibration Analysis System

The Vic-3D™ Vibration Analysis System by Correlated Solutions is a new addition to the Vic-3D product line of measurement solutions. Vic-3D Vibration enables full-field 3D viewing, measurement, and analysis of transient events. Full-field operational deflection shapes in the frequency domain can easily be seen and compared with levels of accuracy in the nanometer range.

What is transient vibration analysis?

Transient vibration analysis is the process of monitoring, measuring, and analysing the condition of samples during a transient event. Material properties can also be observed through the analysis of operational deflection shapes and mode shapes created by the event. These full-field 3D shapes can provide useful information which can be used to improve and correct a sample’s balance, displacement, flexure, rigidity, and overall product performance. Measuring operational deflection shapes can help answer the question: “How much is this structure moving at a particular frequency?”

Why is it important to you?

Operational deflection shapes created from transient tests show how a sample can have nonuniform thicknesses, surface irregularities, weak points, cracks and/or other imperfections & flaws. This information can be useful at any point in the process of achieving your overall goal, from writing a project proposal to testing a functional or failing part in the field: The Vic-3D™ Vibration Analysis System. It has a justifiable price point when writing proposals.

The Vic-3D™ System can be used:

• To create and validate FE models when designing parts & equipment
• During the research and design process
  In the product testing phase
• To provide manufacturing quality assurance
• To certify and assure equipment is operating as expected and required
• To measure and analyse parts post-installation
• To ensure product quality and performance over time and in the field
• When reassessing product functionality over time

Examples of transient events which can be measured are the following:

• Door Slams
• Modal Hammer
• Strikes
• Engine Start-ups
• Drop Tests
• Explosive Testing
• Ballistic Testing

System Features :

• View, compare, animate, graph, extract, and export data for easy FEA comparison
• Measure 3D full-field, high-frequency mode shapes with nanometer resolution
• Measure extremely low amplitudes with extremely high accelerations
• Full-field strain, deformation, and shape variables are still available
• Easy procedures, accurate results
• User-friendly interface
• Only a fraction of the price of a laser vibrometer system

Advantages over other measurement techniques:

While traditional vibration measurement techniques can be useful, they also have many drawbacks. For example, accelerometers can become unglued during testing, can mass-load a sample, and can only provide point-to-point measurements, often only in a single plane. Pre-testing and testing can also take days or even weeks to perform on large structures.

With the Vic-3D™ Vibration Analysis system, there are no adhesives, wires, signal analysers, power amplifiers, or load cells necessary for detailed vibration results. Obtaining thousands of data points for a tiny, complex structure or a large one is as easy as changing a pair of lenses.

Similar to digital image correlation, laser vibrometers can provide a non-contact measurement solution, but similar to accelerometers, they are also only able provide point to point measurements.

A 3D measurement can be achieved with multiple scanning vibrometers, but these are usually mounted on large robot arms, which can take up valuable laboratory space and cannot be moved easily once installed.

Additionally, these systems are unreasonably expensive for many applications. The Vic-3D™ Vibration Analysis system can be taken into the field with any compatible laptop, and together with the Vic-3D™ Workstation, the system can become mobile and secure inside your facility.

Vic-3D Vibration Analysis is only a fraction of the price of a 3D scanning laser vibrometer system, and since the module can be added onto any existing 3D system, it’s even more affordable.
