An inertial vibrator based on an integrated double-coil structure

Abstract

The invention provides an inertia type vibration exciter based on an integrated double-coil structure. The inertia type vibration exciter comprises a movable magnet (1), an upper coil (13), a lower coil (14), plate springs and an outer shell (2), wherein the two ends of the movable magnet (1) are symmetrically arranged annular tubular structures, so that a magnetic field generated by the movable magnet (1) forms a loop along the annular tubular structures; the upper coil (13), the lower coil (14) and the outer shell (2) are of an integrated structure; one ends of the upper coil (13) and the lower coil (14) are symmetrically positioned in two annular holes (17); and when a reverse alternating current is introduced, homodromous electromagnetic excitation force is generated among the upper coil (13), the lower coil (14) and the movable magnet (1), and the movable magnet (1) and the outer shell (2) oppositely move to form vibration excitation. According to the inertia type vibration exciter, the integrated structure of the outer shell and the coils is utilized, so that the heat dissipation capability of the exciter is improved, and the reliability of long-time and high-power work of the exciter is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical vibration, in particular to an inertial vibrator based on an integrated double coil structure. Background technique [0002] A vibration exciter (referred to as an exciter, also known as an actuator) is a vibration excitation device that converts electrical energy into mechanical energy. Driven by an input signal, it excites the target in the form of an output force to generate the expected vibration. With the advancement of technology, in various fields such as scientific research, military affairs, automobiles, entertainment, etc., as people's demand for vibration generation or control becomes stronger, the application of vibration exciters is becoming more and more extensive. [0003] According to the different transducer devices, the exciter can be divided into electromagnetic type, piezoelectric type, magnetostrictive type, hydraulic type and other types. Among them, piezoelectric and mag...
