In Search of the Perfect Crash Test Dummy...

The name comes from: Total HUman Model for Safety.

Toyota Motor Corporation (TMC) announced that the latest version of its THUMS crash test dummy now allows analysts a detailed peek at internal-organ injuries caused by automobile collisions.

THUMS , for over a decade now, has allowed highly detailed analysis of the types of bone, muscle and impact injuries by realistically simulating the characteristics of the human body—ranging from different shapes of the body, its skeletal structure and even the skin. Now, with the advance of THUMS 4 scientists will be able to gather the same information for internal organs. Damage to internal organs accounts for approximately half of all injuries sustained during automobile collisions.

TMC began developing THUMS in 1997 in cooperation with Toyota Central R&D Labs., Inc. The original was launched in 2000. THUMS Version 4, an adult male of average build, adds detailed models of internal organs to the previous version’s elements of bones and the brain, enabling analysis of injuries to a wider range of internal organs.

To develop Version 4, TMC worked with outside research institutes and universities and utilized a high-precision computed tomography (CT) scanner to make detailed measurements of the internal structure of the human body. By creating precise models of various internal organs, as well as the positions of and relations between those organs, TMC created a virtual human model containing approximately 14 times more information than the previous version.

As a result, for analysis of internal injuries, Version 4 can simulate in greater detail how, during a collision, areas of the torso become deformed and internal organs are damaged.

THUMS is used by many automotive manufacturers for analyzing injuries resulting from automobile collisions, applying the results to developing and improving safety devices such as seatbelts and airbags. TMC also plans to add models of a small female and a large male to its virtual-human-model line-up, to enable simulation of a wider range of accident situations. TMC expects to begin selling the latest THUMS this Fall.
