Electromagnetic Shakers: • Operate similarly to an audio speaker • A lightweight fixture attaches to the test structure • Generates force in proportion to input current • Driven by conventional methods using an audio power amplifier • Shaker part numbers shown include the model number of the matching impedance head | | | | | | | | | | Piezoelectric Shakers: • A lightweight fixture attaches to the test structure • Generates force in proportion to input voltage • Driven by high voltage and requires an impedance matching network • The F7 Shaker is built with an integral impedance head | | | | | | | | | | | | | | | | | | | | Shaker | F3 / Z602WA | F4 / Z820WA | F5B / Z11 | F10 / Z820WA | | | | | Electromagnetic | Electromagnetic | Electromagnetic | Electromagnetic | | | | Nominal Force Output | 1 lb. | 10 lbs. | 0.4 lbs. | 20 lbs. | | | | Frequency Range | 25 - 10,000 Hz | 10 - 7,500 Hz | 10 - 10,000 Hz | 5 - 2,000 Hz | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Shaker | F7 | F7-1 | F4 / F7 | | | | | Piezoelectric | Piezoelectric | Dual | | | | Matching Network | N7FS | N8HFS | N7FS | | | | Nominal Force Output | 100 lbs. | 100 lbs. | 100 lbs. | | | | Frequency Range | 500 - 20,000+ Hz | 1 - 80,000 Hz | 10 - 20,000+ Hz | | | | | | | | | | | | | | | | | | | The PA8HF power amplifier, to complete Wilcoxon's Shaker Systems, can be found at our website, www.wilcoxon.com. | | | | | | | | | | www.wilcoxon.com | | | | | | | | | | | | | | | | | | | | | | | | | |
