Abstract

Toyota Motor Corporation and Toyota Central Research and Development Laboratory have been using Total Humans Model for Safety (THUMS) for occupant and pedestrian safety simulation, for vehicle safety research and for vehicle development. THUMS is a finite model (FEM) of whole human being, with the precise shape and similar material property of human boners, ligaments and soft tissues. THUMS does not consist of any rigid body elements and any mechanical joint elements. Ligaments and tendons similar to those of a human being connect the bones and muscles of THUMS. The biomechanical fidelities of THUMS have been validated with the test data that is already available to the public in order to maintain the reliability of the injuries estimated by THUMS. The pedestrians safety simulation using THUMS indicated that the magnitude of the MCL strain for a 50-percentile American THUMS depends on the lower bumper stiffness of the FE model of the saloon type vehicle.
