First seatbelt anchorage test rig to use servo-electric actuators


Newly established company Additium Technologies, which develops a range of high-performance passive safety test systems, recently joined efforts with VTI to develop a new seatbelt anchorage test system, which features servo-electric actuators. The Electrical Seat Belt Anchorage (E-SBA) system is said to be the first full electrical system of its kind in the world.

It is claimed to provide high levels of accuracy and is user-friendly, thanks to its servo-electric actuators, a powerful real-time controller and improved algorithms.

The system can be equipped with up to nine servo-electric actuators and controlled via a force-displacement nested loops controller. The standard version delivers a maximum dynamic force of 30kN at 300mm/s, achieving a balance between performance, peak current consumption and system cost. Stroke is 1,000mm, which is more than enough for typical test sample deformations under load.

The system is said to offer several key advantages over traditional hydraulic systems. It provides much more predictable behavior and easier test setup with straightforward displacement control. It’s also very low maintenance and cleaner, operates silently and is less affected by temperature and humidity variations.
