Dual Axis Electrodynamic Shaker
Servoelectric Dual Axis Electrodynamic Shakers
The Dual-Axis Electrodynamic Shaker from eMpulse Test Systems delivers fast, precise, and efficient vibration testing. By applying vibration in two perpendicular axes simultaneously, it reduces test cycle time, minimizes handling, and provides more realistic simulations of real-world conditions. This system is ideal for both product qualification and high-volume production screening.
- Save Time in Production Screening
In high-throughput environments, every minute counts. Dual-axis vibration cuts test time nearly in half, helping you get parts out the door faster without sacrificing quality. - Reduce Labor and Setup Traditional
3-axis testing requires three separate setups. With a dual-axis shaker, you eliminate one, saving time and reducing handling errors. - Increase Defect Detection Without Overstress
Tailor stress profiles on each axis to detect latent manufacturing issues while avoiding unnecessary damage to parts. - Test Under More Realistic Conditions
Real-world environments apply forces in multiple directions at once. Dual-axis vibration replicates these conditions more accurately than single-axis testing.

Advantages of Servoelectric Single Axis Systems
Extended Stroke and Velocity
Pedestal-style servoelectric actuators provide longer strokes than electrodynamic shakers and achieve higher frequency response than servo-hydraulic systems.
Thermal Management for Extended Testing
High fidelity 32-bit closed-loop control ensures smooth, accurate motion across all test speeds, without switching valve types or control strategies.
High-Frequency Capability
Motor coherence up to 400 Hz enables test profiles that demand high dynamic response, exceeding the capabilities of servo-hydraulic actuators.
Solid Welded Construction
Precision CNC machined and ground surfaces to 0.0001” tolerances to ensure perfect alignment for system longevity. Nickel plating surfaces resist long-term corrosion better than zinc, powder-coating or paint.
Force Range and Modular Design
Modular motor configurations deliver peak dynamic forces from 1 kN to 108 kN, independent of static load. Systems are available in both vertical and horizontal orientations. Vertical shakers include a coaxially mounted air spring that supports static loads without limiting dynamic performance.
Nanometer-Level Accuracy
Integrated displacement feedback systems offer <10 nm resolution, supporting high-precision test requirements.
Sideload Capacity
Outboard bearings significantly improve sideload tolerance, outperforming comparable servohydraulic systems in lateral stability and reliability.
Pneumatic Support
Patented Integrated high volume Air-bag pneumatic support system for no maintenance and long-term durability.
Universal Fit, No Moving Parts No Track-Width Adjustment Required
Wide actuator and wheelpan with outboard bearing placement accommodates nearly all vehicle sizes and completely eliminates the need for Track-width adjustment system
Efficient, Clean Operation
Direct-drive electric motion is up to 80% more efficient than hydraulics, with no fluid handling, reduced maintenance, and a cleaner test environment.
Integrated Safety Features
These features are built into the control architecture to ensure operator safety and specimen integrity during every test cycle. Every system includes comprehensive safety monitoring:
