A horizontal axial angular vibration device, comprising
- a base;
- a moving component, comprising a table surface for disposing a test equipment and a main shaft connected to the table surface to drive the table surface to rotate;
- wherein:
- further comprising:
- a driving component, associated with the table surface and/or main shaft to drive the table surface to swing around the axis of the main shaft;
- the axis of the main shaft is horizontally disposed;
- wherein the driving component is a first driving component, and the first driving component comprises a first moving coil assembly associated with both ends of the main shaft and a first magnetic circuit assembly matched with the first moving coil assembly;
- the first moving coil assembly is mounted on the moving component, and the first magnetic circuit assembly is fixed to the base;
- and when alternating current is applied to the first moving coil assembly, under the action of an air gap magnetic field generated by the first magnetic circuit assembly, an alternating driving torque is generated on the first moving coil assembly, thereby driving the moving component to swing back and forth around a balance position, achieving angular vibration of the table surface;
- wherein the first moving coil assembly is of a whole disc structure, comprising a first substrate and a first coil group fixed on the surface of the first substrate, and the first substrate is fixedly connected to the main shaft;
- the first magnetic circuit assembly comprises an inner magnetic base arranged on the base, an outer magnetic base arranged on the base and corresponding to the inner magnetic base, an inner magnetic steel arranged on the inner magnetic base, an outer magnetic steel arranged on the outer magnetic base, and a first air gap formed between the inner magnetic steel and the outer magnetic steel;
- and the first moving coil assembly is in clearance fit with the inner and outer magnetic steel respectively.
