Decelarator Sled Systems
Seattle Safety (SESA) manufactures large payload sled systems for dynamic testing of automotive and aerospace seating and restraint systems (crash dummy testing).
SESA offers both decelerator and acceleration sled systems capability.
SESA deceleration sled system uses a pneumatically propelled sled and a programmable decelerator that can reproduce a wide variety of crash pulses with excellent predictive accuracy.
SESA also offers integrated facility packages, including: Sled System, Floodlighting, High Speed Photometrics and Triggering.
The Seattle Safety decelerator sled system is available in six basic versions. Other sizes and capacities can be produced as a custom order. Seattle Safety provides the equipment described below along with on-site installation and training.
Decelerator – Mounts to submerged reaction block flush with adjacent floor. Double pulse capable. Highly accurate and flexible wire pattern software included.
Pneumatic Accelerator – Low, near-constant acceleration, typically 0.2–0.4 g with 0-g coast. Variable lengths to suit customers' needs. No civil work typically required.
Sled – Payload attaches directly to sled or to interchangeable, rotatable yaw plate with customer-specified hole pattern.
Track – Variable lengths made to suit customers' needs. 117–189 ft (36–58 m) to date. No civil work required.
Firing – Control valving, gauging, and safety interlock firing switches provided.
Photographic Floodlights – Lighting systems range in capacity from 0.4–200 kW. Types include overhead suspended banks, low-profile portable floor units, adjustable-height portable units, film pit lights, and onboard lights. Also available are computer control and power actuation of overhead suspended banks and integrated time zero strobes.
Camera Outriggers – Hinge-mounted camera outriggers have low profiles and allow easy sled access.
Test Article Fixturing – Established design and manufacturing capability of a wide variety of innovative and convenient customized test article fixturing.
