Experimental modal analysis simplified
RotoVib enables automated and full-body experimental modal analysis using Polytec’s optical 3D scanning laser Vibrometers. Its easy to set-up hardware and software integrates seamlessly into the Polytec scanning vibration measurement workflow and saves time by automatically repositioning the devices-under-test (DUT) instead of a manual and tedious relocation of the sensor setup. 360° measurements of the DUT are as easy as a measurement from just one side.
Highlights
- RotoVib automated modal test station
- Integrates into the CAE workflow
- Creates full-body 3D vibration data set
- Small footprint for lab use
- Accepts part up to 50 kg (110 lb)
- Interfaces with PSV software
- Ready to use – no installation
Automating your modal test
A small footprint and individual positioning of all components enables operation in the lab for small and medium-sized DUTs up to 50 kg (110 lb). RotoVib converts a scanning vibrometer measurement into a software defined test using test geometries from CAE and returning a completed modal data-set and – on demand – an updated geometry of the DUT. A breadboard-style magnetic steel baseplate allows for safe mounting of the DUT and individual instrumentation with automatic modal hammers or inertial shakers.
RotoVib enables test engineers and technicians to carry out automated modal tests with the highest spatial resolution without having to meet special safety requirements, as is the case with conventional robotic systems. The product is particularly suitable for smaller test objects, such as control units or gearbox housings, and offers an efficient solution for acoustic optimization.

The proven PSV QTec 3D Scanning Vibrometers mark the standard for measurement sensitivity in 3D vibration mapping! Their patented QTec® technology uses multi-path interferometry based on infrared (SWIR) laser granting high-fidelity measurements on all surfaces from DC to 25 MHz. PSV QTec significantly reduce testing time - especially on dark, biological, rotating or moving objects, determining operational deflection shapes and Eigenmodes for NVH, acoustics, structural dynamics, ultrasonics, FEM validation and NDT.
PSV Software
The PSV Software is the heart of every Polytec full-field vibration measurement system. This comprehensive software package allows the fast and simple acquisition, display and editing of vibration measurement data gathered with all PSV Scanning Vibrometers, the MSA Micro System Analyzer series for microscopic observations or the automated structural test station RoboVib®.
RoboVib
By combining a 3D scanning vibrometer and an industrial robot, RoboVib® offers you an automated measuring station for measuring everything from complex components to complete vehicle bodies. Both the amount of time required and the sources of error – especially in experimental modal analysis – are reduced significantly. So you can thoroughly test a vehicle body, for example, in just one to two days, whereas you would previously have needed weeks to even prepare for the test itself.
