Ground Vibration Testing
PCB’s focus on tailoring sensors and signal conditioning to specific applications is illustrated by our line of structural test accelerometers and signal conditioners. These products are designed for convenience, accuracy and reliability, whether the test involves extracting the natural frequencies, vibratory modes shapes and damping of a complete vehicle or an operating subsystem, or requires only “quick and dirty” component vibration troubleshooting.
Since this kind of testing typically involves large channel counts, PCB’s GVT specific products include:
- A line of cost effective phase-matched structural accelerometers that feature accessories for simplified mounting. These accelerometers are available in a range of form factors for both single axis and triaxial measurements. High sensitivity piezoelectric force transducers are also available for vibration force control of compliant structures such as satellites.
- Autonomous sensor property identification, using industry standard Transducer Electronic Data Sheet (TEDS). This capability can be further tailored to interface with specialized formats developed by major data acquisition providers. PCB® also offers a bar code reader tailored to the GVT application.
- Cable management and signal conditioning systems including patch panels, multichannel cables, and bank switch systems. These save substantial installation and data management time and money, while allowing large channel GVT’s to be accomplished with a limited number of data acquisition channels.
- Modal Shakers and shaker stands supported by a full line of impedance head systems that measure both the input force and driving point response.
- A full line of instrumented Modal Hammers specifically designed for modal test excitation and force measurement, as an alternative to shaker excitation.
