Abstract

This paper was prepared to assert that coil springs could be useful as displacement sensors as well as mechanical parts. We have investigated the displacement dependence on the inductance of a coil spring and resonance frequency of a simple LC circuit in which a coil spring took a part as an inductor. The changing ratio of inductance to displacement was 6.6 %/㎜. Inductance and/or inductance change of a coil spring was explained with FEM simulation. The changing ratio of the output voltage, which was obtained with the LC circuit, to displacement was estimated to be 6.23 %/㎜.
