CHARACTERISTICS

The smallest of our high-force shakers, V964 offers a high overturning moment coupled with top force ratings, which is why it is ideal for testing satellite systems. Combining an advanced armature fabrication and water-based cooling, it is capable of efficiently delivering optimal acceleration and velocity.

The armature suspension incorporates a unique design to provide cross-axial support and precise control of rotational movements, while a water-cooled wound coil system yields exceptional low-frequency performance with relatively modest amplifier output.

V964 can be operated in a wide range of humidity and temperature conditions and, because it is water-cooled, it is also suitable for cleanrooms (certifiable to Federal Standard 209 Class 100000) and other controlled settings. Moreover, operational costs are generally low, as the closed-loop cooling mechanism minimizes water losses and eliminates the need for expensive air conditioning.

Additionally, the body of the shaker is hermetically sealed and pressurized, which increases efficiency and dependability as this prevents moisture, foreign particles, and other contaminants from getting inside and causing malfunctions and delays. This feature also protects the load support system and ensures that the shaker can safely hold large payloads.

Standard mounting for V964 consists of a trunnion fitted with LDS^® Lin-E-Air suspension that isolates the shaker from the ground, thus reducing vibration on the surrounding environment and permitting operation at low frequencies with minimal seismic interference on test results.

ADDITIONAL CAPABILITIES

Optional guided head expanders increase the mounting surface and allow you to safely and efficiently test loads with offset centres of gravity.

Pairing the shaker with one of our slip tables further extends the system’s testing profile, as it enables vibration in both the vertical and horizontal axes.

Thermal barriers are also available as an option to protect the shaker from high temperatures when used in environmental tests
