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, 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.
