Shaker Accessories
Stinger Set
Modal Shakers do not have test specimens mounted directly on them. Instead, they are attached to the structure using a special component called a “stinger.” The stinger is a thin, flexible rod that transfers force from the shaker to the structure without any interference.
The stinger plays a crucial role in modal testing by improving accuracy. It transmits force in the right direction to the force sensor or impedance head. Its flexibility also protects both the test object and the shaker from harmful forces.
When you get a modal shaker package, it comes with a set of stingers. This set includes stinger rods of different lengths, like 2mm, 2.4mm, and 3.2mm, along with collets and nuts for easy installation.
Stinger adapter for PM Shaker
Thanks to PM-MS converter (PM-MA) and stinger set, you can convert Permanent Magnet shaker to Modal Shaker.
Head Expanders
PM-HE (Head Expander) specifically designed for the PM-100, PM-250 and PM-440 shaker. The PM-HE revolutionizes your testing experience by providing a significantly broader mounting surface. This means that test objects of larger sizes can now be easily attached directly to the shaker platform, expanding the testing possibilities to a whole new level.
Crafted from robust aluminum, the PM-HE-100 exhibits exceptional strength-to-weight ratios, ensuring both durability and lightweight convenience. PM-HE-250 and 440 is made from magnesium and extremely lightweight.
With these remarkable attributes, the PM-Head Expander dramatically enhances the shaker’s testing capabilities, unlocking a multitude of diverse applications.

In certain scenarios, testing products solely in the Z axis may prove inadequate. To address this need for horizontal axis excitation in shakers, the implementation of a Slip Table becomes essential. Recognizing this requirement and aiming to amplify the testing capabilities of our shakers, Dynalabs proudly offers our esteemed customers a Slip Table that seamlessly integrates with our 440N capacity shaker.
The design of our Slip Table is meticulously tailored to complement our shaker, ensuring optimal performance and robust construction through a coupled form. Moreover, our shaker is ingeniously engineered to detach from the slip table and effortlessly rotate into a vertical position, allowing for the seamless utilization of both vertical and horizontal tests.
Blower (Shaker Cooling System)
Shakers consume a significant amount of electricity and this energy is highly converted into heat. For this reason, cooling of the field coils and armature coils is mandatory in electrodynamic vibration systems.
DynaLabs small PM and MS shakers with integrated amplifiers (20N and 100N) don’t need external cooling system. Passive cooling is enough (natural convection). But for continuous operation at 20N and 100N forced cooling is suggested. For larger shakers (250N and 440N) a blower is needed.
