The V200 Series electro-dynamic vibration generators are miniature units designed to reproduce a vibration environment under laboratory conditions. They are also suitable as non-seismic pick-ups and are widely used in educational and research establishments to investigate the dynamic behavior of structures and materials. Other applications include fatigue and resonance testing, used as velocity transducers or high speed actuators and various medical purposes.
V200 series vibrators can be driven by any suitable oscillator/amplifier combination, but the Ling Dynamic Systems PA25E amplifier is specially recommended for this purpose. Being of the permanent magnet design, the V200 series vibrators do not require a field power supply. A typical system incorporating the V200-PA25E combination is shown in Figure 1.1.
The vibrator can be base or trunnion mounted and an auxiliary suspension is available, at extra cost, for use when the weight of the test package exceeds the table suspension rating.
