英文摘要：

The experiment of solid granules medium pressure and the testing equipment was designed and manufactured. The pressure distributing laws were obtained through the experiment. The load model of the sheet under the drawing pressure was established：the linear load model and quadratic function load model.The sheet forming die set was designed and manufactured, Work pieces contours show that the shape of free forming area could be represented accurately by parabola function. The free areas＇ plastic forming before attaching-die was analyzed thoroughly in the process of solid granules medium sheet forming. The formulas for calculating the free areas＇ stress were gained. This study laid a foundation for plasticity theory research of the solid granules medium sheet draw and bulge forming.
