Retractor Durability Cycler

This machine is used for performing durability tests on seatbelt retractors. We also make an environmental version of this machine.



6 stations - 2 independent closed-loop servo motors control 3 stations each. Each station may be automatically declutched to allow other stations to continue testing when one part fails.

Webbing Lock & Loose Belt Detection - Proximity sensors are provided on each station to detect when the retractor locks or if there is a reduction in the belt tension. The software may be programmed to monitor and log the occurrence of these conditions and can optionally stop the test.

Impact simulation - Pneumatic controlled sleds are used to simulate vehicle impact of 1.0 G (0.25 G). Each motor may be programmed to simulate webbing acceleration up to 5.0 G.

Programmable Waveshapes - Each step of the test may be programmed to use either a Sine, Constant Velocity (up to 4500 mm/s) or Acceleration movement. A specialized abuse test is also provided that does a low-level webbing acceleration up to a given velocity and then accelerates the webbing at 5.0 G.



Auxiliary Electrical and Pneumatic Outputs - Connections are provided to allow additional features to the testing process. The software can be programmed to control these outputs at various steps in the testing process.

Various Reporting Styles - Error and machine events are logged in a file during a test. This data may be formatted as event, summary or batch reports for viewing and printing.

Prelock Detection - The software will detect and attempt to correct premature locks during the test. The prelock errors are counted and added to the test report.

Touchscreen - Oversized buttons and controls allow all machine operations to be performed using the standard touchscreen display.

Flexible Test Construction - Each test is built by breaking the test down into steps and saved to a file. These parameter files may be linked together to produce a testing sequence.
