Dual Shaker Systems

Designed to test payloads for a defence customer, the Dual LDS V850-440 SPA24/56K special Vibration Test System has been engineered for coupled operation. Each shaker is fitted with a Guided Head Expander that allows interfacing to the customer’s specialised payload. A steel truss rigidly connects the shakers together.

To ensure the dual system is mobile as required by the customer, each shaker base is integrated with Airglides allowing the full shaker assembly to be moved effectively on a cushion of air.

The special LDS Pneumatic Control Stands provide the operator with shaker body and armature position display and control. Shaker armature and body position are automatically controlled to ensure that the complete system remains balanced.

Both shakers can be used either individually or in the standard dual (pushpush) configuration; the LDS Multiple Amplifier Control (MAC) System allows this. Each shaker is driven to a tight amplitude and phase tolerance of the other to ensure consistent application of vibration, minimising cross-coupling and ensuring system and payload safety.
