Mobility Testing

In mobility testing, accelerance, mobility and compliance functions are calculated. For structures with well-separated modes, estimation of natural frequencies and damping ratios is possible. Often done during troubleshooting using hammer testing.

Shakers 4808, 4809, 4810

Shakers 4808, 4809, 4810

Type 4809

Portable Vibration Exciter (or shaker) capable of delivering peak sine forces up to 60 N (13.5 lbf). Type 4809 is the ideal solution for vibration testing small components, or in-field experimental modal analysis.

Type 4809

This benchtop vibration exciter offers versatility and dependability for a range of applications, including mechanical impedance and mobility measurements and accelerometer calibration.

Type 4809 features a wide frequency range (10 Hz – 20 kHz) and a continuous displacement of 8 mm (0.32 in) peak-to-peak. It can impart 45 N (10 lbf) of sine force – or up to 60 N (13.5 lbf) with assisted cooling.

Our 75 VA Power Amplifier Type 2718 has been designed specifically to drive this vibration exciter; however, Type 4809 can also be powered without forced-air cooling by any third-party amplifier with the adequate voltage rating.

To meet your exact testing needs, Type 4809 can be customized with a range of accessories, including trunnions, power amplifiers, nylon stingers and push-pull rods, force transducers and impedance heads.
