    Abstract
  • Buffer material plays an important role in the hypervelocity launching experiments. By using numerical calculations, the influence of TPX buffer material's thickness on high impedance tantalum flier plate's velocity is analyzed, and the optimal thickness of buffer material is also evaluated. For thickness of 0.3 mm and 0.5 mm tantalum flier plate, the relative error of tantalum flier plate's center velocity is about 5%~6% at different thicknesses of the TPX buffer materials. In order to compare the influence of different buffer materials on tantalum flier plate's velocity, the two-dimensional results of tantalum flier plate's center velocity and pressure histories are calculated at the same thickness of TPX and Lexan buffer.
