摘　　要：本文在深入研究了三维网格重分技术的基础上 ,针对轴类锻件的网格重分提出了一种简洁、有效的算法———投影组合法 ,并用等参逆变换法对重分前后的场量进行转换。模拟实例表明 ,该算法生成的网格质量好、数据转换精度高。Based on the study of three dimension remeshing technlogy, a compact and effective algorithm , a method of projecting and assembling , is proposed for the remeshing of shaft forging. The state of field is mapped by isoparametric inverse method. The simulation of crank shaft shows that the scheme can generate well shaped mesh and keep a high mapped precision.
