Abstract
The invention provides a magnetoelectric Coriolis force detection sensor. The magnetoelectric Coriolis force detection sensor comprises a shell, a mass body disposed in the shell and a detection sensor mechanism disposed in the shell. The shell is adopted as a rotation system with an angular velocity shown as (omega vector). The mass body m moves relative to the shell at a velocity (velocity vector). The detection sensor mechanism is used for achieving angle detection. The magnetoelectric Coriolis force detection sensor achieves detection of low or high broadband rotating speed of a translational rotator (the shell) according to the Coriolis Effect. As Fc vector = - 2m[(omega vector)*(velocity vector)], when the m is established, the value of the Coriolis force is determined by the movement velocity (velocity vector) of a mass point (the mass body) and the angular velocity (omega vector) of the rotation system (the shell). Accordingly, when the (omega vector) is low (the translational rotator slowly rotates) or when the (omega vector) is high (the translational rotator rotates fast), optimized corresponding frequency spectrum relationship between the (omega vector) and the (velocity vector) can be obtained by correspondingly increasing or decreasing the movement velocity (velocity vector) of the mass point and the stable Coriolis force can be obtained, thus achieving detection of low-speed or high-speed rotation of the translational rotator.
Description
technical field [0001] The invention relates to the technical field of force detection sensors, in particular to a magnetoelectric Coriolis force detection sensor. Background technique [0002] We know that 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] Do not find description or report similar to the present invention at present, also do not collect similar data both at home and abroad. Contents of the invention [0004] The present invention provides a magnetoelectric Coriolis force detection sensor aiming at the above-mentioned deficiencies in the prior art. [0005] The pre...
