  • High Frequency Vibration Testing Electrodynamic Shakers

    High Frequency Vibration Testing Typical electrodynamic shakers have a usable frequency range up to 20003000 Hz. For higher frequency applications UD engineers have developed two different shaker systems optimized for sine & random vibration tests up to 5000+ Hz. and extreme SRS shock events out to 10000 Hz. !

  • Hydraulic shakers astretech

    High frequency (200 Hz sine or even higher) hydraulic shakers usually sacrifice the large stroke feature. Why not leave the high frequency job to electrodynamic shakers? It is because for a same ( large) driving force a hydraulic shaker is significantly cheaper than an electrodynamic shaker.

  • What is High Frequency and Why Do We Use It?

    What is High Frequency and Why Do We Use It? Topics Services . High frequency (also known as the Tesla high frequency current) was first developed in the late 1800's by a renowned scientist Nikola Tesla. While it offers a number of functions before the invention of "modern" antibiotics it was largely used for medical purposes such as in the

    Frequently Asked Questions Modal Shakers and Related Topics

    For applications of general vibration testing with large shakers current is generally considered to be a fairly good estimate of the force applied to the system. However for modal testing the shaker is set up with a stinger to attach the shaker to the structure.

  • Piezoelectric Shaker Development for High Frequency

    Piezoelectric shakers are well suited to generate such motion and are suitable for use with laser interferometric methods at frequencies of 3 kHz and above. An advantage of piezoelectric shakers is the higher achievable accelerations and displacement amplitudes as compared to the electrodynamic (ED) shakers.
