Abstract
This paper describes experimental tests in LARM2 in Rome to analyze impacts on a human head. The tests consist of performing three different types of impact by hitting a commercial head mannequin with a rigid object. Inertial Measurement Unit (IMU) sensors and force sensors measure each impact’s effect and evaluate the results. The sensors are located on suitable head points to monitor force, acceleration, and angular displacement on small and large lateral impact and top impact events. Results of tests are discussed to investigate and characterize the biomechanics in human head impacts. Considerations from results are used to formulate a new criterion for head-neck injury by impacts.
Highlights
Head injuries are related to traffic collisions, runovers, contact sports, and daily life actions. e frequency of these events is high, and in some cases, the consequence could be fatal
HIC (Head Injury Criteria) and NIC (Neck Injury Criteria) are the most commons for the events presented in this work. ese indexes evaluate the acceleration and velocity on the head and neck, respectively, during impact and estimate the injury’s severity [7,8,9]. is paper presents a low-cost impact device developed in LARM2 in Rome to evaluate and characterize the biomechanics in human head impact for safety index formulation [10] and testbed designs [11,12,13]
Test performed by the impact device developed in LARM2 in Rome consists of evaluating the head impact on the most commons events: lateral impacts and top impacts
