Servoelectric Road Simulators
Servoelectric Road Simulators
At eMpulse Test Systems, our servoelectric road simulators precisely replicate real-world driving conditions, from urban streets to off-road environments. With configurations up to 108kN, they simulate varied road surfaces, terrains, and environmental factors, supporting 4-Poster, body-coupled, and aero loading applications.
Engineered for high accuracy and efficiency, our systems integrate with acoustic and climatic chambers for NVH, temperature, humidity, and solar testing. Utilizing SEA technology, they deliver superior control, reduced maintenance, and up to 80% energy savings over hydraulic systems. The seaPLUS series boosts efficiency by 46%, further extending performance, durability, and testing capabilities. Designed to meet SAE, ISO, and other industry standards, these systems provide reliable, high-fidelity testing for a range of automotive applications.

Advantages of Servoelectric Road Simulators
Extended Wheelpans
Pedestal style servo electric linear motors are fitted with extended wheelpans for vertical motion into the tire patch for the typical Four Poster system configuration.
Thermal Management for Extended Testing
Increased efficiency in converting electrical to mechanical energy, results in significantly lower heat generation. This improved efficiency reduces the size of the active cooling infrastructure, minimizes thermal loading on components, and contributes to lower overall operational costs.
Body Coupled Actuation
Additional body coupled actuators can inject higher frequency vibration directly into the vehicle frame.
Tired Coupled Actuation
Available in configurations for 2, 3, 4 or more tire coupled actuators, in addition to direct body coupled actuators or aeroloaders.
High-Frequency Capability
Motor coherence up to 400 Hz enables test profiles that demand high dynamic response, exceeding the capabilities of servo-hydraulic actuators.
Force Range and Modular Design
Modular motor configurations deliver peak dynamic forces from 1 kN to 108 kN, independent of static load.
Nanometer-Level Accuracy
Integrated displacement feedback systems offer <10 nm resolution, supporting high-precision test requirements.
Pneumatic Static Load Support
Supports the vehicle weight, which allows the motors to provide the full dynamic force capacity independent of vehicle weight.
Pneumatic Support
Patented Integrated high volume Air-bag pneumatic support system for no maintenance and long-term durability.
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.
Track-Width Fit
Wide actuator and wheelpan with outboard bearing placement accommodates nearly all vehicle sizes and completely eliminates the need for Track-width adjustment system in most cases.
Internal Cooling Motors
Internal motor cooling allows higher continuous force capacity to run extended or durability test profiles.
High Fidelity
High fidelity 32-bit closed-loop control ensures smooth, accurate motion across all test speeds, without switching valve types or control strategies.
Application-Specific Software
Integrated with eMpulse controls that feature application-specific software, seaPLUS Road Simulators are ideal for field data reproduction, sine sweep, or Power Spectral Density (PSD) profile replication.
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:
