Toyota Offers Free Access to THUMS Virtual Human Body Model Software

JCN Newswire (English)
Toyota Motor Corporation (Toyota) announced today that it will
make its Total Human Model for Safety (THUMS) software freely
available from January 2021 as part of its efforts toward a safe
mobility society. THUMS is a virtual human body model software
program for computer analysis of human body injuries caused in
vehicle collisions. Free access to THUMS, and subsequent use by a
wider variety of users, is expected to enhance vehicle safety.

Designed to aid vehicle safety technologies' research and
development, and developed in cooperation with Toyota Central
R&D Labs., Inc., THUMS was the world's first virtual human body
model software when it launched in 2000. It enabled simulation and
analysis of injuries caused in vehicle collisions. Since then, and
up until the latest Version 6 was released last year, it has
continually evolved to add a range of models with different
genders, ages and physiques that include skeletal structures,
brains, internal organs, and muscles. Compared to the physical
crash dummies commonly used in vehicle collision tests, THUMS is
able to analyze collision-related injuries in more detail, because
it precisely models the shapes and durability of human bodies.
Conducting simulations on computers also enables repeated analysis
of a range of different collision patterns, while it can
dramatically reduce development lead times and costs associated
with collision testing.
THUMS is currently used in vehicle safety research by over 100
vehicle manufacturers, suppliers, universities, research
institutions and others, in Japan and overseas. It is being used to
research and develop many different safety technologies, such as
seatbelts, airbags, and vehicle structures that help reduce injury
risks in vehicle collisions with pedestrians. Vehicle safety
assessment organizations are also currently considering the use of
THUMS for virtual testing in their future assessment plans.
Making THUMS freely available is expected not only to enable a
greater number of people to use it in their vehicle safety
research, but to also improve the usability of the software, as
users make improvements to the model themselves and share the
results with others.
Seigo Kuzumaki, Fellow at Advanced R&D and Engineering Company,
offered the following comment about free access to THUMS: "Since
the very first launch of THUMS in 2000, we've been making ongoing
improvements and avidly working to better reproduce the human
anatomy and expand the variations of models. It has now become
indispensable technology to Toyota's efforts in developing safety
technologies and vehicles. We decided to make the software freely
available to have more people use it, to further enhance vehicle
safety across the entire automotive industry, and to help reduce
traffic injuries and fatalities to create a safer society. We look
forward to seeing it applied broadly in development sites and
others, envisioning a mobility society with automated vehicles and
other technologies, moving forward."
Software license sales through JSOL Corporation (Tokyo) and ESI
Group (Paris) will come to an end during 2020, with the start of
free access to THUMS.
THUMS Version 4: Models
Models include detailed human anatomy (skeletal structures, brains,
internal organs, etc.) in a range of genders, ages, physiques, and
postures.
Note: Versions 4, 5, and 6 will be made available for free
