Permanent magnet shaker by B&K is a versatile, dependable solution

The LDS V406 permanent magnet shaker

Brüel & Kjær test and measurement tools are available in Canada through Durham Instruments. This includes the innovative LDS V406 permanent magnet shaker, which is a popular option for general vibration tests and in universities and research facilities. This device is recommended for a wide range of industrial applications.

The LDS V406 is a great option for fatigue and resonance testing for small electronics, the study of biomedical devices and materials, and related tasks.

Designed for maximum performance

The unit also works as a non-seismic pickup, velocity transducer, or high-speed actuator. The LDS V406 is a versatile and dependable solution designed for maximum performance. Durham Instruments particularly recommends it for use in the general manufacturing, aerospace, automation, food-processing, forestry, medical, military, mining, packaging, power-generation, alternative-energy, and transportation industries, and also in research and development.

This permanent magnet shaker has a usable frequency range from five to 9,000 hertz, and it provides a nominal peak sine rating of 98 newtons when supplied as standard. The LDS V406 can produce a sine vector force of 196 newtons when combined with the recommended LDS PA500Lamplifier and cools with an external fan. With an armature diameter of 38 millimetres, the instrument incorporates a robust yet lightweight moving armature with sufficient support for test loads, without undermining force capability. Two laminated-fibre flexures are bonded to the device to afford the armature with axial support and enhance lateral and rotational restraints.

The LDS V406 is usually base-mounted, with trunnion mounting available too. Users can add an auxiliary suspension unit for vibration screening on large, spring-mounted structures. This allows the shaker to hand vertically from the device under test, increasing payload capacity. The auxiliary suspension enables obverse movement, unlike with standard operation. Other common uses for the Brüel & Kjær LDS V406 permanent magnet shaker:

• accelerometer calibration
• fatigue and resonance testing
• laboratory experiments, including powder separation or compacting
• machinery condition monitoring and vibration measurement
• modal and structural analysis, including civil engineering applications like bridge testing
• testing of medical devices and materials
• vibration screening of small components and testing of electronic assemblies
