Durham Instruments supplies a wide range of world-class test and measurement tools by Brüel & Kjær, including the LDS V406 permanent magnet shaker. This device is a popular option for general vibration tests and in universities and research facilities, and it is also suitable for a broad variety of industrial applications. Brüel & Kjær recommends the LDS V406 for fatigue and resonance testing of small electronics, the study of biomedical devices and material, and related applications.
Wide usable frequency range
The LDS V406 also functions as a non-seismic pickup, velocity transducer, or high-speed actuator. The device is a versatile and reliable unit built for maximum performance. Durham Instruments deems it suitable for use in such sectors as general manufacturing, aerospace, automation, food processing, forestry, the medical field, the military, mining, packaging, power generation, alternative energy, and transportation.
This permanent magnet shaker has a usable frequency range from five to 9,000 hertz, and it offers 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 paired with the recommended LDS PA500Lamplifier and cools with an external fan. With an armature diameter of 38 millimetres, the shaker incorporates a robust yet lightweight moving armature with enough support for test loads, without undermining force capability. Two laminated-fibre flexures are bonded to the instrument to afford the armature with axial support and enhance lateral and rotational restraints.
The device is typically base-mounted, but trunnion mounting is available. An auxiliary suspension unit can be added for vibration screening on large, spring-mounted structures. This allows the shaker to hand vertically from the device under test, boosting payload capacity. The auxiliary suspension allows obverse movement, unlike with standard operation.
