- Water-cooled LDS high force shakers
- Air-cooled LDS medium force shakers
- Air-cooled LDS low force shakers
With peak force ratings from 89 kN to 289 kN the water-cooled electrodynamic shakers provide comprehensive, long-duration testing capabilities for use in the automotive, aerospace, defence, electronic and electrical machinery production sectors. These systems have been used in single and multi-shaker configurations, and are suited to test products such as satellites and missiles.
Uses of Electrodynamic Vibration Shaker System
- High force, long duration automotive testing
- Avionics and military hardware testing
- Low-frequency and shock pulse testing
- Product and package testing
Features
- Designed to test heavy loads at high levels over long continuous periods reducing test time and expense
- Full displacement at full force
- Compatible with AGREE/CERT standard thermal chambers.
- For demanding shock tests. e.g. 100gn 11ms
- Two-coil design reduces rotational turning moments and ensures superior performance
- Vibration control at low-frequencies
With peak force ratings from 8.9 kN to 60 kN the air-cooled electrodynamic shakers are industry standard for automotive, military and electronic testing. They provide the versatility and capability demanded by research and development, product qualification and stress screening.
Uses
- Automotive parts and systems – qualification testing
- Electronic assembly, computer equipment testing
- Avionics and military hardware testing
- Satellite component testing
- Product and package testing
- General stress screening
Features
- Interchangeable armatures extend diameter from 185mm to 335mm for vibration testing large or multiple payloads
- Internal load support is standard
- LDS active suspension system
- Airbag and rubber isolation mountings available for the vibration table
- LDS Lin-E-Air body isolation and guidance system available for the vibration table
- Useful vibration control frequency range from d.c. to 3500Hz.
- Maximum sine vibration force ratings: – 9.8 kN (2200 lbf)
With peak force ratings from 667 N to 5,115 N these air-cooled electrodynamic shakers are suitable for vibration testing of small to medium sized payloads, such as small automotive components and electronic assemblies. Utilising LDS’s unique suspension system with rolling-strut and flexure to ensure excellent cross axis restraint, these proven vibration tables provide cost-effective product qualification and instrument calibration.
