Séminaire : Virtual Human Driver - Digital Human Body Model for Riding Comfort Simulation

Hyung Yun Choi (PhD Standford en 1991), Professeur au département de mécanique et système de la conception à l'Université d'Hongik, donnera un séminaire mardi 18 octobre à 14h dans l'amphithéâtre A207.

Titre:  Virtual Human Driver -- Digital Human Body Model for Riding Comfort Simulation

Résumé: We present our ambitious R&D study, which aims to develop an advanced digital human body model to simulate active response of human vehicle driver such as voluntary and reflexive actions for maintaining upright driving posture against vibratory and lateral G forces respectively coming from road surface roughness and vehicle turning. It will be a progressive feature to the existing human body model at Pam-Seat which is already cable of predicting human driver’s responses in occupant-seat interactions but rather restricted to passive mode, e.g., seating pressure distributions and transfer functions. The “virtual driver” project has been carried out in two main phases, i.e., first, experiments with test subjects to identify and quantify driver’s active response which is then followed by modeling and implementation of numerical active muscles into the digital human body model in Pam-Seat. This presentation will mainly focus on the experimental findings but also include some preliminary result from recent feasibility study on active joint model which would be a key hurdle to a successful development of the virtual driver model.
