Moita, P.P., Barradas Cardoso, J. e Valido, A.J. (2013), “Limiting performance analysis of a vehicle restraint system”, Proceedings of the International Conference on Structural Engineering Dynamics (ICEDyn 2013), 17-19 Junho, Sesimbra, Portugal
In this paper the limiting performance analysis of a vehicle restraint system is studied. A discrete model of the human thorax is used. The driver displacement relative to the dashboard is minimized and several injury criteria are required to remain bellow a safety threshold value. The optimal control force acting on the driver is found. A design and control sensitivity analysis formulation is derived for mechanical systems. The equations of motion and the sensitivity equations are integrated at-once as it is typical for the static response. Mathematical programming is used for the optimal control process.
