Product catalog summary
Overview
The RoboVib® Structural Test Station is an advanced system designed for automated experimental modal testing, significantly reducing time and cost associated with traditional methods. It utilizes laser-Doppler vibrometry for high-density, non-contact vibration measurements, ideal for optimizing noise and vibration characteristics in product development.

Key Features
  • Automated Testing: Integrates a 3D Scanning Vibrometer with a multi-axis industrial robot, allowing for automated data acquisition and reducing test times from weeks to hours.
  • High Precision: Laser-based measurements eliminate mass loading and allow for high-density measurement points, enhancing model validation at higher frequencies.
  • Flexibility: Capable of measuring complex components and complete vehicle bodies, with the ability to tailor the system to specific requirements.
  • Data Integration: Supports interfaces for incorporating FE geometry, external sensor data, and modal analysis, streamlining the CAE data workflow.

Workflow
The RoboVib workflow consists of three main steps:
  1. Preparation and Setup: Define measurement grid using FE models and set up the robot path.
  2. Automated Data Acquisition: Conduct unattended measurements by positioning the robot and scanning segments.
  3. Analysis and Post-Processing: Analyze and display data, export for modal analysis, and update FE models.

Performance and Customization
The system offers a frequency bandwidth of up to 25 MHz in 1D-mode and 5 MHz in 3D-mode, with a velocity range up to 30 m/s. It supports MIMO capability and data handling in common file formats. Optional enhancements like the PSV Xtra improve optical sensitivity and measurement capabilities.

Applications and Support
RoboVib is suitable for lightweight and complex shaped structures, providing full-field measurements with high spatial resolution. Polytec offers support and customization options through their global offices, ensuring the system meets specific application needs.

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 simple...

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 PSV-500-3D...

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 human...
