Based on the study of vibration method in ice detection

through building the physical model and mathematical model of the vibration tube ice sensor

giving out the calculation formula of the inherent vibration frequency by axes of vibration tube

analysising the design by the MATLAB imitation software

the sample designing of the ice sensor is accomplished.The ice sensor is made of permanent flexibility alloy material which have magnetostriction ability.Vibration tube in the magnetic field vertically brings about magnetostriction under the effect of alternate magnetic field

that is axis resonance.When the ice appeared in the surface of the vibration tube

it causes the offset of inherent frequency

we can know the ice state by detecting the offset of inherent frequency.
