RoboVib® Structural Test Station RoboVib® Structural Test Station Automated Experimental Modal Testing Product Brochure

RoboVib® Structural Test Station Automated Experimental Modal Analysis to Save Time and Cost By mounting a 3D Scanning Vibrometer to a multi-axis industrial robot, RoboVib removes many of the limitations of traditional contact transducer methods. RoboVib is engineered for measuring anything – from complex components up to complete vehicle bodies. With RoboVib you can automatically acquire and record the data necessary for a modal analysis which can be indispensable for the development of new products. This technological symbiosis drastically reduces test times for experimental modal...

Fast and Precise per Laser By using a laser as the vibration probe, RoboVib takes data with zero mass loading, eliminating the inaccuracies and complexities associated with mounting and removing traditional contact sensors. At the same time, the number of measurement points is not limited by the sensor size and the number of available measurement channels. This allows a higher density of measurement points and a model validation at higher frequencies. The measurement points can be determined using the Scanning Vibrometer software or imported directly from the FE application. The setup is...

RoboVib® Structural Test Station Flexibility Through Robots Customized to Your Needs Using the PSV-500-3D Scanning Vibrometer, vibration data for deflection shape analysis of the visible part of the object are acquired segment by segment. To measure a car body or any complex shaped object, the scanning heads are repositioned several times to cover all views. Each of the partial measurements or views is then stitched together to make a complete picture of the car body. A RoboVib Structural Test Station can be tailored to your requirements and measurement tasks. The basic setup comprises a...

Define Measurement Grid Import from FE Model Analysis and Post-Processing Analyze and Display Data Export for Modal Analysis Teach Robot Path Define Segments Automated Data Acquisition Scan Segment The RoboVib® Workflow Step 1 starts with the setup using a measurement grid from the FE model. Step 2 comprises the fully automated test cycle, moving the laser scanning heads from position to position scanning each segment. Every measurement point directly refers to a FE nodal point. The segmental data is stichted together, resulting in a common data set based on the FE nodal information. No...
