An integrated dual-rotor lead screw electromechanical inerter

Abstract

An integrated double-rotor lead screw electromechanical inerter, including reverse double-screw screw shafts, outer rotor components, inner rotor components, armature windings, permanent magnets and an armature control circuit connected to the armature windings, the armature The windings and permanent magnets are separately arranged on the outer rotor assembly and the inner rotor assembly. The reverse double screw screw shaft includes a forward rotation section and a reverse rotation section. The inner rotor assembly and the outer rotor assembly are threaded with the forward rotation section and the reverse rotation section respectively. The outer rotor assembly and the inner rotor assembly are rotationally connected through a thrust bearing; one end of the reverse double-screw screw shaft is fixedly connected to the movable joint, and the other end is slidably installed in the fixed joint, and the fixed joint is rotationally connected to the outer rotor assembly through a thrust bearing ; The reverse double-screw screw shaft drives the inner rotor assembly and the outer rotor assembly to rotate in opposite directions, the armature winding generates induced electromotive force, and the induced electromotive force acts on the armature control circuit. The invention has the advantages of improved performance and stability of the inerter and compact structure.

Description

technical field [0001] The invention relates to an inerter, in particular to an integrated double-rotor lead screw electromechanical inerter. Background technique [0002] Inerter is a mechanical inertia element with two terminals proposed in recent years. It is widely used in the field of vibration isolation technology, such as suspension, building anti-shock and absorbing dynamic mechanical vibration. In the electromechanical analogy theory, the inerter can be completely similar to the capacitor in the circuit network, so the theoretical method of circuit network synthesis can be used to guide the design of the mechanical network. In the mechanical network synthesis, the inerter can replace the role of the mass block and is completely similar to the capacitor in the circuit network synthesis. The "imaginary mass" simulated by the inerter is called the inertial mass coefficient, and the ratio of the inertial mass coefficient to the real mass of the inerter is called the in...
