An air-cooled electrodynamic shaker designed for vibration and mechanical shock testing of medium-sized articles, such as automotive components and electronic assemblies. It can support payloads up to 160 kg (353 lb) and deliver maximum forces of 9.81 kN (2205 lbf).
Widely used in R&D by the automobile and aerospace & defence sectors, LDS® V830 medium-force shakers combine industry-standard ratings and versatility to offer comprehensive solutions for a variety of vibration test scenarios that include general stress screening, product qualification, and product and package testing.
Sine force peak: 9.81 kN
Max random force RMS: 9.81 kN
Max acceleration sine peak: 75 g
Velocity sine peak: 2.0 m/s
Displacement continous pk-pk: 50.8 mm
Moving element mass: 12.05 kg
Usable frequency range: DC – 3 kHz
Capable of delivering superior force and velocity performances with low capital and running costs, the V830 shakers have a usable vibration control frequency range from DC to 3.5 kHz. They can perform high-acceleration shock tests as well as tests using sinusoidal, random and transient excitations.
The two available versions feature lightweight, robust armatures that can be interchanged to extend the diameter – from 185 to 335 mm (or, from 7.28 to 13.19 in) – and enable the shaker to accommodate a broader range of loads for testing.
The larger-diameter V830-335 affords excellent overturning restraint, ensuring that larger or multiple devices under test are safely fastened when the shaker is used with a slip table. The smaller model, V830-185, is suitable for high g-force vibration control applications, such as drop tests and crash simulations.
An active suspension mechanism improves reliability at low frequencies and eliminates the need for additional resilient mountings. Its unique infrared system allows accurate control of the armature position in both vertical and horizontal operation, which is crucial for high-quality shock testing where the armature must be offset.
All shakers in the LDS® V800 series are compatible with AGREE chambers and can be integrated with other equipment for use in environmental tests. To protect the shaker when operating at high temperatures, thermal barriers can be added.
The shakers can be outfitted with a number of choices to meet your specific needs: mounted on an air-isolation trunnion with body rotation gear box (as standard), combined with one of our oil-film slip tables to enable horizontal testing, or base-mounted for under-chamber operation.
