摘要
Magnetically driven solid liner convergence is an important means to carry out research of fluid dynamics in laboratory. Electromagnetic loading is suitable for carrying out regular and serialized physical experiments because of its high loading efficiency, high repeatability and high adjustability. FP-2 facility uses 48 modules of capacitors to store energy. Under the condition of charging voltage of ±40kV, the peak current in load can reach 10.5 MA, and the aluminum liner with diameter of 60-90mm can be driven to a speed of 5-7km/s. According to the driving ability of FP-2 facility, the load structure is optimized to meet the needs of different physical experiments through program simulation. Combined with X-ray photography and laser velocimetry, many physical experiments such as material strength, adiabatic shear and jet mixing were carried out. In the material strength experiment, the disturbance growth image of physical target and the velocity history curve of interface are obtained. In adiabatic shear experiment, the loading speed history is obtained and the experimental samples are recovered. The experimental results validate the repeatability, reliability and stability of the loading capacity of FP-2 facility, which lays a foundation for further study of hydrodynamic phenomena and material properties.
