Servoelectric Actuator (SEA) damper testing systems

Testing, type approval and certification solutions for vehicles

About SEA automotive damper testing systems

Servoelectric actuator (SEA) damper testing systems assess the performance, durability and service life of essential automotive components including shock absorbers, dampers and struts. SEA automotive damper testers are frequently used during research and development to evaluate different materials for their suitability in various applications and scenarios. Damper testers are also used to check the quality during the production process thus ensuring that only components that meet the highest standards are delivered to the customer.

SEA damper testing systems are a major improvement over the servo hydraulic technology previously used across the automotive industry. SEA-based damper testing systems offer a clean, efficient and dynamically responsive solution for both performance and durability testing.

The key benefits of SEA-based damper inspection and testing technology include:

  • Energy efficiency
  • Quiet operation
  • Precise and full digital control with built-in diagnostics
  • High continuous dynamic force capacity
  • High bandwidths
  • Liquid or air-cooling
  • Multiple measurements, control algorithms and configurable inputs/outputs

TÜV SÜD is your trusted SEA automotive testing partner

TÜV SÜD is widely recognised as a leading partner in damper inspection and SEA automotive testing systems and is the partner of choice for many global vehicle manufacturers. Our highly skilled technicians have built state-of-the-art SEA damper test systems to reveal any faults on your vehicles and components and provide recommendations on how you can improve and enhance dampers and other vehicle components.

We offer a global presence and have testing facilities close to auto-industry manufacturing plants around the world, meaning we can provide a flexible and responsive knowledge service. With our experience in auto testing, we draw on our in-depth knowledge to provide you with transparent and impartial advice and designing of SEA damper testing system, allowing you to provide the best product for your customers.

TÜV SÜD’s SEA-based damper test systems make use of the latest technology. They include two standard models offering varying peak dynamic force capacities SEA.10.200 – 10.3kN (2,328lbf); SEA 20.200 – 20.7kN (4,652lbf)), and achieve significantly higher continuous loads, making them the only electric option for extended durability testing. Standard and custom configurations are available for various applications, including:

  • Damper characteristics

  • Strut/shock testing

  • Spring testing

  • NVH component testing

  • Full spectrum of waveform

  • Road profile/time history playback

  • High velocity configuration (up to 8.7m/second)

TÜV SÜD’s SEA damper testers come with Microsoft Windows®-based DAMPER TEST control and analysis software, which generates a full spectrum of waveforms, including sinusoidal, triangle, square, random, frequency sweeps and other custom waveforms. The software also allows road profiles and time history data to be imported and replayed. Our SEA systems take advantage of fully integrated digital processing, without introducing electrical noise inherent in analogue conversion processes, providing more precise control as well as more comprehensive troubleshooting, diagnostic and monitoring tools.
