Modal Shakers
Modal testing can be performed with modal hammers or shakers. If high-frequency excitation content or signal-controlled testing is desired, then modal shakers are the only excitation solution. DEWESoft modal shakers are lightweight and powerful modal shakers which can go up to 15,000 Hz and provide force levels up to 440N with a maximum 25mm stroke.The series of DEWESoft modal shakers covers a wide range of structures for dynamic characterization from electronic boards and sub-components to machinery, vehicles and aircraft, even constructions.
Advantages:
- Modal stinger can be easily adjusted by the through-hole armature
- Lightweight, durable, portable and easy to use
- Adjustable trunnion base provides high flexibility
- Up to 25mm stroke and broad frequency range
- Modal shakers can be used for Modal testing and Structural Dynamics. Modal Testing is a prerequisite for design and product validation in aerospace and automotive industries as well as many others.

Inertial Shakers
The shakers used in modal testing and in-flight tests of aircraft are usually electrodynamic shakers. However, the traditional shakers are not very portable and the attachment process takes time. DEWESoft inertial shakers are easily mounted and have great mobility. It can be used as a handheld.
Advantages:
- Compact and lightweight design
- Superior low-frequency performance
- Any angle mounting
- Low friction bearing guided
- Inertial shakers are used for Vibration and Modal testing. Inertial shakers are used for testing car chassis, squeaks and rattle testing in cars, civil engineering prototype testing, building structures, floor loading resonances, ships’ flight decks, helicopters rotor simulation, submarines, geophysical surveys, and vibration cancellation systems.
