Small Shakers

Dynalabs permanent magnet shakers are compact, lightweight and powerful general-purpose shakers which can be used for modal and vibration testing. They have high DUT capacity despite their small sizes. DYN-PM-20 and PM-100 has an integrated amplifier and a sine wave signal generator where the frequency can be adjusted from 1 Hz to 15,000Hz.

Advantages:

• Lightweight, durable, portable and easy to use
• Adjustable trunnion base provides high degree of flexibility
• Broad frequency range
• Embedded power amplifier and signal generator
• Technical Specifications
• External Amplifiers Specifications
• Blower Specifications

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. Dynalabs 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.

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
• Technical Specifications
• External Amplifiers Specifications
• Blower Specifications

Inertial shakers and modal shakers are similar in usage area. They are used also in tests for examining vibrational behavior of structures such as modal shakers. However, compared to the modal shakers, the connection styles are different. The inertial shaker’s own body vibrates. For this reason, inertial shakers are fixed directly to the structure. It is easier to use than modal shakers.

Advantages:

• Compact and lightweight design
• Superior low frequency performance
• Any angle mounting
• Low friction bearing guided
