Modal and Inertial Shakers

Dewesoft Modal and Inertial Shakers for Modal and Vibration Testing Applications

Dewesoft now have a full range of available Modal and Inertial shakers with integrated and easy to use amplifiers. Firstly, there are several different types of models are available.   From Permanent Magnet Shakers, Modal Shakers and Inertial Shakers.

Features of Modal and Inertial Shakers:

  • Integrated Amplifier
  • Integrated Signal Generator
  • Trunnian and Handles for great positioning
  • Integrated Screen (Only with an integrated signal generator)
  • Small amplifier box for inertial shakers

Permanent Magnet Shakers

The Permanent Magnet Shakers are compact, lightweight and powerful general purpose shakers which can be used for modal and vibration testing.  They come with an integrated amplifier and sine wave generator.  The frequency can be adjusted from 1 Hz to 15,000 Hz.  Permanent Magnet Shakers are for vibration testing; shock testing, sensor calibration, separation and compacting of powders, fatigue and resonance testing, velocity transducer or high speed actuator and mechanical impedance measurement.

Modal Shakers

Dewesoft’s Modal Shakers are for high frequency excitation content or signal controlled testing.  They can go up to 15,000 Hz and provide force levels up to 440N with a maximum 25mm stroke.  Lightweight, durable, portable, easy to use, and can be adjusted by the through hole armature.   Dewesoft Modal Shakers covers a wide range of structures for dynamic characterisation from electronic boards and sub components to machinery, vehicles, aircraft and even construction.

Electrodynamic Shakers

Electrodynamic Shakers are usually used in modal testing and in the flight tests of aircraft, these traditional shakers are not portable and the attachment process takes time.  However, Dewesoft Inertial shakers mount easily and have great mobility with their compact and light weight design.  Mounted at any angle and provide a low friction guided bearing.  Inertial shakers are for testing car chassis, squeaks, rattle testing in cars, civil engineering, prototype testing, building structures, ship flight decks, floor loading resonances, helicopters, rotor simulation, submarines and vibration cancellation systems.
