Dashboard support with vibration-damping feature
TLDR
A dashboard support for a motor vehicle, including a support beam extending between windshield pillars of a vehicle body, is described in this paper, where a controller is connected to the piezoelectric elements.Abstract:
A dashboard support for a motor vehicle, includes a support beam extending between windshield pillars of a motor vehicle body. Associated to the support beam is an active arrangement, which includes ceramic piezoelectric elements and a controller operatively connected to the piezoelectric elements, for implementing a vibration damping.read more
