Toyota Motors Corporation, the Japanese auto giant, in their statement today announced to open- source their Total Human Model for Safety (THUMS) software from next year, to boost their on-going effort in forming a safe mobility society. The THUMS virtually simulates human body models to analyze injuries faced by human bodies as cars collide. Providing free access to the software and in turn, used by a broader range of users, is anticipated to uplift vehicle safety. With of aim of assisting research and development related to vehicle safety technologies, THUMS was the pioneer software designed with cooperation from Toyota Central R&D Labs., Inc., in the year 2000. The software provided modeling and analysis to human bodies as a result of vehicle collisions. Since its release, it is continuously being updated until the last year, when its version 6 was released. During its up-gradation through the years, it now provides a range model such as gender selection, varying age, and physiques including the skeletal structure, brain, other body parts, and muscles. In contrast with the physical crash dummies that are typically employed during the vehicle collision test, THUMS can readily provide analysis about injuries with more in-depth insights, due to its precise modeling the geometry, shape as well as the durability of the human body. Computer simulations also provide the user with the ability to repeat the analysis with varying collision patterns, resulting in significantly reducing the development lead times along with the economic benefits as compared to collision testing.
The Evolution of Total Human Model for Safety (THUMS)
To enhance vehicle safety the software is being used by more than 100 vehicle manufacturers, suppliers, academicians, and researchers, throughout the world including Japan. The software is currently being used in research and in the development of various safety technologies, ranging from airbags and seat belts to the structure of the vehicle that aids in lessening the risk of injuries as vehicles collide with the pedestrians. Organizations for vehicle safety assessment are also in view of using the THUMS for virtual testing in their plans ahead. Giving free access to THUMS is projected to improve its usability along with the wider community of researchers in the field, as users tend to refine the software and public the outcomes. A research fellow at Advanced R&D and Engineering Company, sharing his views on giving free access to the THUMS software is reported to have praised the move as a significant leap towards safety vehicles research. He further commented that this will eventually lead to lesser traffic injuries and fatalities and make a safer society. He hoped that free access will also result in its broader usage and it will aid in building automated vehicles and similar technologies.
The JSOL Corporation (Tokyo) and ESI Group (Paris) currently hold the right to sell the license to the software and this contract to sell license will finish 2020, as the software will be free to access from the start of 2021.
THUMS Version 4: Models
The models in version 4 of the software provide thorough human anatomy such as it includes skeletal structures, brains, several internal body organs, etc.) With an option to choose gender, select ages, physiques, as well as sitting postures.
Free access will be provided to previous versions 4, 5, and 6.
