In this paper, a novel Uniform Pressure Actuator (UPA) is designed and analyzed based upon the manufacturing technique of pulsed magnets, which has high forming efficiency as well as high strength. The UPA is a specially designed coil for use in electromagnetic forming (EMF) process, which offers a uniform pressure distribution in flat sheet forming. To improve the strength of the coil,...
Pulse current driven forming (PCDF) is a forming method that directly loads a pulse current into two parallel placed workpieces, and the mutually exclusive electromagnetic force between them causes the workpieces to be deformed. Compared with electromagnetic forming (EMF), this method can improve the current density in a low-conductivity workpiece. However, the magnetic field is low due to the...
The Direct-Current Current Transformers (DCCTs), which is based on the magnetic flux compensation, are the most sophisticated instruments to measure currents. In order to achieve the precision measurement of the magnet current in the flat-top pulsed high magnetic field (FTPMF) facility, the DCCT based on magnetic modulator with the range of 30kA is developed. In the conventional high...
High magnetic fields is a basic and indispensable research tool, which has been used in physics, medicine, biology, and other corresponding sciences as an extreme condition. Wuhan National High Magnetic Field Center has been working on the research of high pulsed magnetic field and designed the 100 Tesla system to achieve higher magnetic field. The magnet adopts a three-coil structure, which...
Wuhan National High Magnetic Field Center (WHMFC) has been working on high pulsed magnetic fields and designed the 100 Tesla magnetic system. The magnet adopts a three-coil structure and the outer coil is powered by a pulse generator rectifier. In order to ensure the temperature rise of the coil is reduced, the energy stored in the coil needs to be quickly released after the combined magnetic...
Cu-Ag and Cu-Nb composites, which have been successfully used in high field magnets, reach their most desirable strength level when their interface spacing is below 100 nanometers. The usual fabrication methods for these composites are either cold rolling or cold drawing, both of which refine interface spacing and create anisotropy. These methods may also introduce shear-bands into the...
