Numerical Models of Anthropomorphic Test Devices to Investigate Human Related Impact Events

Anthropomorphic test devices are frequently used to design structures proficient in guaranteeing the survivability of the passengers during potentially fatal accidents such as crash landings. Objective of the present research has been the development of advanced numerical models of aeronautical Hybrid III ATDs. In a first phase, the numerical model of a Hybrid III 50 th percentile was validated: at the beginning, considering the ATD part-by-part so to meet the requirements for the homologation and, then, referring to a down test carried out to assess the performances of an aeronautical Hybrid III ATD. Hence, the reliability of the model was further verified referring to the homologation test of a helicopter seat. In a second phase, the same approach was applied to the validation of the models of a Hybrid III 5th and 95th percentile. Eventually, a comparison among the results obtained considering the homologation test of the helicopter seat and using the three different models was proposed and, in view of that, a number of related conclusions were drew.
