[EN] A novel thermo-physiological human head simulator for headgear testing was developed by coupling a thermal head manikin with a thermo-physiological model. As the heat flux at head-site is directly measured by the head manikin, this method provides a realistic quantification of the heat transfer phenomena occurring in the headgear, such as moisture absorption-desorption cycles, condensation, moisture migration across clothing layers. Before coupling, the opportunities of the head manikin for representing the human physiology were evaluated separately. The evaluation revealed reduced precision in forehead and face temperature predictions under extreme heterogeneous temperature distributions and no initial limitation for simulating temperature changes observed in the human hysiology. This work has been supported by the State Secretariat for Education, Research and Innovation (SBFI C11.0137) under the grant COST Action TU1101 project (http://www.bicycle-helmets.eu/) The authors gratefully acknowledge Dr. Matthew Morrissey and Rolf Stampfli from Empa (St. Gallen, Switzerland) for their valuable contribution to programming of the coupling interface and Barbara Koelblen from Empa (St. Gallen, Switzerland) and Warsaw University of Technology (Warsaw, Poland) for providing the validation data and consultation.
