Wilcoxon manufactured vibrator
Vibration exciter for structural analysis and modal testing.
This vibrator, also known as a shaker, generates a dynamic excitation force that acts according to the principle of mass response. The basic principle involves a component of the vibrator with a large mass vibrating due to a drive signal from a power amplifier, which in turn generates an action force that vibrates the test specimen. 【Low-Frequency Electrodynamic (Electromagnetic) Vibrator】 This electrodynamic (electromagnetic) vibrator operates similarly to a conventional acoustic speaker. A coil is driven within the magnetic field of a permanent magnet, allowing the dynamic electrodynamic coil to vibrate components with very large mass. 【High-Frequency Piezoelectric Vibrator】 This piezoelectric vibrator utilizes a piezoelectric ceramic disc to generate excitation force proportional to the supplied voltage. The disc is mounted in a sandwich configuration between a heavy object and a lightweight plate, which is then attached to the test structure. Although the displacement is very small, by using a high drive voltage and multiple discs, it generates excitation forces at very high frequencies.
