A permanent magnet electrodynamic shaker for vibration testing of small assemblies and electronics, fatigue and resonance tests, and modal and structural analyses. Capable of imparting forces up to 489 N (110 lbf).
The LDS® V455 range has been developed to offer you a shaker that features a higher force rating yet is still suitable for laboratory testing. Ideal for industry, they are also used in universities and research institutions for a variety of medical applications and to study the dynamic behaviour of structures and materials. They can also be employed as velocity transducers or high speed actuators.
Sine force peak: 489 N
Max. random force RMS: 294 N
Max acceleration sine peak: 117 g
Velocity sine peak: 2.5 m/s
Displacement continuous pk-pk: 19 mm
Moving element mass: 0.426 kg
Usable frequency range: 5 Hz – 7.5 kHz
The design of these permanent magnet shakers has been optimized so that they can perform at impressive peak forces and accelerations over a wide frequency band. Although external cooling is not required for the V455 models, a fan unit can be added to cool the shakers with forced air. This significantly increases their force ratings, enabling them to deliver sine forces up to 489 N (110 lbf) – as opposed to 178 N (40 lbf), when naturally cooled.
They incorporate a robust-yet-lightweight moving armature that ensures adequate support for test loads without undermining performance capability. Two laminated-fibre flexures are bonded to the armature to provide it with axial support and to enhance lateral and rotational restraints.
As standard, the shakers come base-mounted; however, they can be mounted onto trunnion frames that allow adjustment of the axis of vibration through a 90-degree range. Optional rubber mountings are also available upon request.
The V455 shakers can be driven by compact, quiet and energy-efficient amplifiers, such as LDS® PA1000L, and is compatible with LDS® LASERUSB™ and COMETUSB™ vibration controllers, as well as with third-party control systems.
