The V875B and V875T are base or trunnion mounted electrodynamic shakers used for sine, random and transient vibration testing, used in conjunction with an LDS SPA40K amplifier.
Interchangeable lightweight armatures offer a cost-effective solution to high-performance shock and vibration testing. Our larger diameter lightweight armatures provide excellent overturning restraint when testing large or multiple payloads, with the smaller diameter versions suitable for high 'g' vibration control applications. Compatible with AGREE norms, LDS V800 series models can be integrated with other environmental test equipment such as thermal and humidity chambers.
LDS active suspension system eliminates the need for resilient mountings and improves reliability at low frequencies. A unique infra-red system allows accurate control of the armature position in both vertical and horizontal operation, essential for high quality shock testing where the armature must be offset. LDS Lin-E-Air body isolation ensures excellent stability of the vibration table at low frequencies. Guidance shafts eliminate the tendency of a vibration test system to rock while testing large or offset payloads at low frequency.
