ADICO feature introduction

(1) The key performance of the system:

◎High first-order resonance frequency and wide use frequency

Optimized design of the moving coil frame structure, especially the strengthening design of the weak links such as the traditional structure of the moving coil frame force transmission angle plate, which effectively improves the force transmission rigidity; the composite fixed winding ring barrel and the winding ring connected by glue joint and screw are adopted. The new structure of the wire loop cylinder to strengthen the glue hole enhances the rigidity of the winding. Significantly improve the first-order common vibration frequency of the moving coil, which exceeds that of similar international products.

◎High reliability of moving coil winding

  The original new structure and new technology of the moving coil winding reinforcement ring significantly improve the vibration resistance of the moving coil winding in high thrust, high acceleration vibration, shock and high temperature environments.

◎High air cooling efficiency

Innovative design of the cooling air duct of the electric platform: the air inlet structure is improved, the upper magnetic ring uses a long slot type air inlet instead of a round hole type air inlet; the excitation coil adopts a honeycomb air duct, and the middle magnetic ring adopts a double-layer shunt air The new structure such as the oblique wedge-shaped air duct is adopted for the channel and the lower magnetic ring, which significantly improves the cooling effect.

◎Cooling fan

  The cooling fan has a unique structure design such as air duct, the fan has good cooling effect and low noise.

◎The power amplifier adopts IGBT module

  The power amplifier adopts reliable IGBT module, which has high stability and reliability.

◎Safety performance

  The product meets the European standard test requirements, and the power amplifier is equipped with an emergency stop switch to effectively respond to emergencies. Comply with the safety requirements of American UL and European Union CE.

(2) The characteristics of the vibrating table body:

1. Double magnetic circuit structure: Compared with single magnetic circuit, the magnetic field is strong, the volume of the table is small, and the magnetic leakage is small.

2. Frameless moving coil: Because the moving coil frame is omitted, the active system is light in weight, has a large no-load acceleration, and the first-order resonance frequency of the moving coil is high, so that the waveform distortion of the whole frequency band is small, and the moving coil has good heat dissipation.

3. Suspension device: Roller arm suspension system and linear bearing guidance make the vibrating table have good guiding performance and better anti-eccentric load ability. Trunnion vibration isolation: when vertical vibration, special foundation can be omitted.

4. Choose air spring support with low dynamic stiffness and high static stiffness: strong load-bearing capacity and good low-frequency characteristics.

5. The moving coil of the system adopts aerospace materials (high strength and light weight), new structure, new technology, new concept (finite element design, analysis), which enhances the rigidity and strength of the moving coil, and improves the first-order axial direction of the moving coil. Resonance frequency.
