1.Introduction
VT series Permanent Magnetic Vibration Exciters are the high-quality, compact machine with a permanent magnetic field. It is designed for long, trouble-free operation, and has a force rating from 10N to 1000N enabling relatively heavy loads to be excited to high g levels. The moving element is supported by a robust rectilinear guidance system consisting of grouped radial and transverse flexures in a unique construction. The flexures are made from a bonded sandwich of spring steel and a damping elastomer, providing a clean acceleration waveform with low cross motion and low distortion characteristics.
2.Applications
These electrodynamic vibration exciters are typically part of the vibration test equipment used in educational, research and laboratory environments.
l Vibration testing
l Mechanical impedance measurements
l Educational demonstrations
l Structural response testing
l Modal analysis
l separation and compacting of powders
l small component vibration screening
l Vibration transducer calibration
