Development of an electrodynamic velocity sensor for active mounting structures

Pfeffer, Daniel and Hatzfeld, Christian and Werthschützky, Roland Institut für Elektromechanische Konstruktionen (Corporate Creator) (2011):
Development of an electrodynamic velocity sensor for active mounting structures.
In: Eurosensors XXV, Athens, Greece, 4.-7. September 2011, [Conference or Workshop Item]

Abstract

The authors present a velocity sensor based on the electrodynamic principle. It is designed to utilize active damping in an engine mounting structure. To design the magnetic circuit, a new dimension, the winding-density free transducer constant X_wdf, is introduced and implemented in numerical field simulation software as an optimization parameter. Based on these simulations an electrodynamic transducer with a constant of 22.1 T*m in the frequency range of 10 … 200 Hz is realized. Using simple electronics, this sensor offers a cost-effective alternative to other means like laser vibrometry with an error of less than 1 %.
