Abstract

New actuator concepts are required in order to improve the safety of vehicles and to benefit from modern crash sensor systems. Pre-crash applications in particular call for re-usable actuators. The following article describes approaches for using smart material based actuators to influence the crash performance of a vehicle without the disadvantages of conventional restraint systems. One of these concepts from the Fraunhofer-Institute for Structural Durability and System Reliability (Fraunhofer LBF) — a reversible linear actuator working with shape memory alloys — is presented in detail.
