Electrodynamic Shakers and accessories
SignalForce Products Comprise Turn-Key Vibration Test Systems that Include: Electrodynamic Shakers (both Air- and Water-Cooled), Power Amplifiers, Slip Tables, Head Expanders, Fixtures, and Thermal Barriers for Environmental Testing
Data Physics sales and support are adept at understanding user applications and providing properly configured vibration test systems to meet both current and future needs.
All SignalForce vibration test systems, or vibration shaker systems, including accessories such as head expanders and slip tables, are manufactured in the USA or the UK by Data Physics. Service is provided from both direct and partner service centers located around the globe, with direct service centers on both coasts of the USA, the UK, China, and India.
Air Cooled Shakers
Force outputs from 2 lbf (9 N) to 15,000 lbf (66.7 kN)
Air cooled shakers are lower cost, more versatile and easier to install and maintain than water cooled shakers. Air cooled shakers are workhorses for sine, random, shock, transient mixed mode and long time history replication applications. High displacement options are available for requirements such as transportation testing and classical shock testing. High lateral and torsional stiffness ensure maximum stability and support.
Water Cooled Shakers
Force outputs from 16,000 lbf (71 kN) to 50,000 lbf (222 kN)
Water cooled shakers are typically used for larger payloads and more demanding structural testing applications. By utilizing dual hydrostatic bearings, payloads with high overturning moments can be tested without the need for external guidance systems. Water cooled shaker systems generate comparably lower acoustic noise output and lower demand on facility HVAC systems. Water cooled shaker bodies are completely sealed, making them ideal for both clean room and hazardous environments.
Force outputs from 7 lbf (30 N) to 56 lbf (250 N)
Structural excitation of large structures can often present considerable challenges. The Data Physics line of inertial shakers can be mounted onto a large mechanical or civil structure to generate forces for dynamic response measurements. The inertial shakers can also be used for active noise cancellation applications. Inertial shakers are completely self-supporting and can be mounted onto the structures at any angle. The central spigots are connected to the structure and the shaker body provides the inertial mass.
Force outputs from 18 lbf (80 N) to 475 lbf (2.1 kN)
Modal shakers are used to excite a structure via the central spigot with a connecting rod (stinger) so that energy can be input without the mass or dynamics of the shaker affecting the response of the structure. The GW Series modal shakers exhibit almost zero axial stiffness through the use of a linear guidance bearing. They also bear no load and have no suspension system.
