Abstract

The invention provides a geostrophic force effect based translational velocity or acceleration sensing device and structure, wherein a drive structure and an electromagnetic coil interact to drive a sensitive magnetic structure to rotate, when the sensing device has translational velocity meeting a condition of generating a geostrophic force effect, the sensitive magnetic structure generates deflection; a sensing mechanism converts the deflection displacement into an output electric signal. The invention innovatively applies a function sensitive material and a geostrophic effect to the translational velocity or acceleration detection, realizes a novel translation detection mechanism and method, and can be used for realizing a reciprocating translation detection means without detection stroke limitation.

Description

technical field [0001] The invention relates to the technical field of detection sensors, in particular to a translational velocity or acceleration sensing device based on the Coriolis force effect and a combined structure thereof. Background technique [0002] According to the theory of Newtonian mechanics, taking the rotating system as the reference system, the tendency of the linear motion of the particle to deviate from the original direction is attributed to the action of an external force, which is the Coriolis force and is defined as: In the formula is the Coriolis force; m is the particle mass; is the velocity of particle motion; is the angular velocity of the rotating system. [0003] The existing detection sensor based on Coriolis force, for example, the publication number is 103913158A, the publication date is July 09, 2014, and the Chinese patent application titled "Magnetoelectric Coriolis force detection sensor" provides A magnetoelectric Coriolis force...
