Information
Using our servoelectric actuators (SEA), eMpulse Test Systems road simulators are designed to replicate real-world driving conditions, including road surfaces, terrain, and environmental factors.
We offer a range of systems that can simulate a wide variety of driving conditions, from city streets to highways to off-road environments. In addition to traditional 4-Poster testing applications, we also offer optional body coupled and aero loading actuation. Our road simulators can be integrated with various chamber types including acoustic attenuation for ambient NVH testing or a climatic chamber capable of temperature, humidity, and solar simulation.
The seaPLUS series by eMpulse Test Systems offers superior efficiency and extended performance. With a 46% higher performance over previous systems, the seaPLUS series widens the performance gap between our servoelectric technology and comparable hydraulic systems. seaPLUS further enhances durability and expands testing capabilities across a wider range of applications and industries.
The key benefits of seaPLUS road simulation testing technology include:
Improved Reliability: A less complicated actuator assembly resulting in fewer parts yields an increase in reliability and lower maintenance costs.
Higher Accuracy: SEA systems are not affected by many physical constraints that cause reduced system accuracy and repeatability. These variables include oil viscosity changes with temperature, accumulator pressure, servo valve wear, flow restrictions, seal friction, hydraulic resonances, and oil contamination. Increased Performance: seaPLUS can achieve higher velocities at higher forces, with 3X higher frequency response, resulting in lower RMS errors than hydraulic systems.
Greater Efficiency: In comparable use cases, SEA systems use less than 20% of the electrical energy compared to hydraulic systems.Safer Operation: The seaPLUS eliminates the potential for high pressure oil leaks and related environmental pollution. The SeaPLUS also utilizes safety integrated functions that allow for safety limited acceleration, velocity and force (current) to be configured for specific applications or testing.
Improved Troubleshooting: Smart diagnostics capability within the controls can direct operators to the specific hardware causing a fault condition. Remote log-in capability allows eMpulse engineers to aid in troubleshooting anywhere in the world.
Reduced Maintenance: Servoelectric actuators are compact, easy to install, and require minimal maintenance, resulting in lower overall system costs.
Cleaner Environment: Hydraulic fluids can be hazardous to the environment, and the process of disposing of used fluids can be costly and complex. Servoelectric systems do not require any fluids, making them a cleaner and safer alternative.
