K-Series Electrodynamic Shaker Systems

K-Series high performance, electrodynamic shaker systems offer 100% air cooling, 3 inch (76 mm) stroke, and feature an output force up to 17,000 pounds (75.6 kN). They are available with a 16 inch (445 mm) or 24 inch (654 mm) armature outer bolt circle, allowing a variety of package sizes and fixture configurations. The K170 shakers contain a host of new, high performance features and enhancements, including an upgraded armature suspension design. A dual in-line post bearing, and shear mount elements, provide increased structural integrity, and off-axis restraint allowing the K170 to meet the demands of today’s long stroke, low frequency vibration tests.

Air Cooled

All of the K-Series system configurations are totally air cooled, an important feature that reduces the cost of installation and operation. Both the SAI Series power amplifier and the K170 electro-dynamic shaker are cooled by forced air. Quiet mode circuitry is available for Buzz, Squeak & Rattle applications.

3 inch (76 mm) Continuous Displacement

The K170 Series shakers are rated for 3 inch displacement, a requirement for many transportation vibration specifications and for long duration shock pulse testing.

Internal Load Support

2,500 lbs (1,136 kg) internal pneumatic load support including automatic armature centering is provided standard on all K170 Series Shakers, allowing testing of a wide range of package sizes.

Head Expanders

For applications involving large and heavy payloads, the K170-16 can be fitted with an optional guided head expander. Designed for 2,000 Hz operation, these head expanders include integral linear bearings and additional pneumatic load support.

Combined Environment Testing

The K170 Series is very popular for applications requiring combined environment testing, specifically combinations involving temperature, humidity and vibration. All three base options support combined environment testing allow simple integration with chambers manufactured by all of the leading thermal chamber companies worldwide. Thermal barriers, an oil conditioning system for slip table, and remote system startup from an external contact closure are available.
