Shaker Accessories
Head Expander for PM-100
Head expander is designed for PM-100 shaker. PM-HE provides broader mounting surface so that test objects will be larger which will be attached directly to the shaker platform.
PM-HE structure is aluminium. Thus, it has high strength-to-weight ratios. Based on these features PM-Head Expander increases shaker testing capabilities and provides shakers to be used in more diverse applications.
Head Expander for PM-250 and PM-440
Head expander is designed for PM-250 and PM-440 Dynalabs shakers. PM-HE provides broader mounting surface so that test objects will be larger which will be attached directly to the shaker platform.
PM-HE structure is magnesium. Thus, it has high strength-to-weight ratios. Based on these features PM-Head Expander increases shaker testing capabilities and provides shakers to be used in more diverse applications.
PM-MS Adapter and Stinger Set
Thanks to PM-MS converter (PM-MA) and stinger set, you can convert Permanent Magnet shaker to Modal Shaker.
Stinger adapter for PM Shaker
No test specimen is mounted on Modal Shakers. Modal shakers are mounted to the structure with stinger and force is transferred from the shaker to the structure via this stinger. Stinger prevents interaction between structure and shaker.
Stinger is essentially a thin, flexible rod that improves the accuracy of modal testing by transmitting force in the axial direction to the force sensor or impedance head. Thanks to its lateral flexibility, it also protects both the DUT and the modal shaker from critical forces.
All modal shaker packages include one stinger set. In this set, there are 2mm, 2.4mm, 3.2mm long stinger rods, collets and nuts.
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.
