Medium-Force Shaker

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.

USE SCENARIOS

• Qualification testing of automotive parts and systems, including ISO/TS 16949, SAE, and other standard tests
• Electronic assembly and computer equipment testing
• Avionics and military hardware testing, such as Mechanical Environmental Tests AECTP 400, MIL-STD and ISO 9000 tests
• Telecommunication and satellite component testing
• General stress screening, such as ISO 5344, ALT, HAST, HASS and others
• Product and package testing, like ISTA and ASTM 4169

CHARACTERISTICS

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.

ADDITIONAL CAPABILITIES

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.
