Abstract

The invention provides an integrated lead screw electromechanical inerter, which includes a lead screw shaft, a nut rotor, a stator, an armature winding, a permanent magnet and an armature control circuit connected to the armature winding, and an Thrust bearing, the permanent magnet is arranged on the nut rotor, the armature winding is arranged on the stator, the nut rotor is threadedly matched with the screw shaft, the linear motion of the screw shaft drives the nut rotor to rotate, the The armature winding generates an induced electromotive force when the nut rotor rotates, 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 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 inertial mass ratio....
