该文根据冲压加速器边界形状复杂的特点，利用贴体网格的弧长参数生成法，将计算域分块生成网格，而后拼接起来。用三次插值函数控制边界的网格点疏密分布，利用新方法将子块光滑拼接，为进一步研究冲压加速器的流场奠定了基础。
According to the complicated shape of the stamping accelerator boundary, this paper makes use of the arc-length parameter generation method of the body-fitted grid to segment the calculation domain into blocks and then spliced them together. The cubic interpolation function is used to control the density distribution of the grid points in the boundary and the new method is used to connect the sub-blocks smoothly, which lays the foundation for further research on the flow field of the stamping accelerator.
