摘　　要：模拟了5种不同曲率半径ASC射流成型与侵彻半无限靶的过程,提出了ASC射流侵彻"三区域"理论,定义了ASC切割能力;研究结果表明:ASC在不同的位置具有不同的射流成型状况和靶板侵彻深度;不同曲率半径ASC侵彻深度均呈现明显区域特征,分别为曲率敏感区、稳定侵彻区、侵彻加强区;稳定侵彻区"平台高度"可作为ASC切割能力,但应高度重视小曲率半径ASC曲率敏感区侵彻深度;本模型中,曲率半径ρ大于80 mm时,ASC切割能力为稳定侵彻区"平台"高度26.5 mm。The processes of ASC with 5 kind of curvature radius jet formation and penetration into half- infinite target were simulated. Three region theory of ASC jet penetration was proposed and cutting capacity of ASC was defined. Research results show that ASC presents different jet formation condition and target penetration depth in~ different position; ASC with different curvature radius presents evident region characteristic consistently in penetration depth, including curvature radius sensitive region, stable penetration region and penetration fortified region; ASC cutting capacity is defined by platform height of stable penetration region and much attention should be paid to small curvature radius ASC. In this model, when curvature radius is p 〉 80 mm, the ASC cutting capacity is platform height （26.5 mm） of stable penetration region.
