The Revolutionary Use of X-Ray Technology in Mercedes-Benz Crash Tests

Mercedes-Benz has recently made a significant impact in the automotive industry through the successful implementation of the first-ever crash test utilizing x-ray imaging technology. This remarkable achievement took place at the EMI research crash facility in Freiburg and has set a new standard in safety testing.

A prominent feature of this test was the use of high-speed x-ray technology to observe internal deformation processes in real-time. According to the company’s official website, this demonstration of technology highlighted the vast potential of x-ray imaging in capturing dynamic internal movements during crash scenarios.

In the course of the test, a SID II dummy representing a female occupant was deliberately positioned on the left-hand side to simulate the impact. The SID II dummy is specifically designed for side impact tests, and its inclusion in this pioneering test further underscores Mercedes-Benz’s dedication to gender-inclusive safety measures.

This groundbreaking x-ray technology has been in development for several years and has recently achieved a significant breakthrough. The utilization of a linear accelerator with a photon energy of up to 9 megaelectron volts has enabled the examination of all materials commonly used in vehicle construction. Notably, the linear accelerator has the capability to produce a continuous stream of x-ray pulses, capturing up to 1,000 images per second. This marks a monumental advancement compared to traditional medical x-ray procedures, ushering in a new era in crash test imaging capabilities.

During the crash test, the x-ray beams emitted penetrate through the car’s bodywork and any test dummies, while a flat detector positioned beneath the vehicle acts as a digital image receiver. As the radiation reaches the detector, it generates an electrical signal, the intensity of which depends on the absorption by the vehicle and dummy structures. This process results in the generation of grey values, similar to x-ray inspections conducted at airports or medical facilities.

Ultimately, the results of the test reaffirmed Mercedes-Benz’s steadfast commitment to occupant safety. The high level of protection offered to occupants was evident as the passenger cell and high-voltage battery of the test vehicles remained undamaged. Through this remarkable demonstration, Mercedes-Benz has established a new benchmark in crash testing and safety standards within the automotive sector.

This pioneering use of x-ray imaging technology in crash tests underscores Mercedes-Benz’s dedication to innovation and excellence in vehicle safety. The successful integration of high-speed x-ray technology has the potential to revolutionize the future of safety testing, paving the way for enhanced protection of vehicle occupants. As the automotive industry continues to evolve, Mercedes-Benz’s ground-breaking approach to crash testing sets a remarkable precedent for the prioritization of safety and technological advancement.
