The Total Human Model for Safety (THUMS) is a finite element human body model intended for injury analysis. The model was jointly developed by Toyota Motor Corporation and Toyota Central R&D Labs. Inc.
The model aims to simulate ‘human body kinematics’ and ‘injury on human body’ in response to a large impact in a car crash. The geometries of the structurally complex human body parts – including the head, torso, joints and organs – are represented by finite element meshes. Material properties have been attained from published literature which has been validated by component testing.
From January 2021, Toyota Motor Corporation made the THUMS model freely available as part of its efforts toward a safe mobility society. Free access to THUMS, and subsequent use by a wider variety of users, is expected to enhance vehicle safety.
Information for how to obtain the model can be found at the THUMS website.
