1、摘要ANSYS 有限元软件包是一个多用途的有限元法计算机设计程序，可以用来求解结构、流体、电力、电磁场及碰撞等问题。因此它可应用于以下工业领域：航空航天、汽车工业、生物医学、桥梁、建筑、电子产品、重型机械、微机电系统、运动器械等。传动轴是最常件的零件，该零件结构较为简单，操作方便，加工精度高，价格低廉，因此得到了广泛的使用。目前很多传动轴都做了适当的改进，使其适用性得到了更大的提高。.本设计是基于ANSYS软件来汽车传动轴行分析。与传统的计算相比，借助于计算机有限元分析方法能更加快捷和精确的得到结果。设置正确的模型、划分合适的网格，并合理设置求解过程，能够准确的
2、获得分析模型各个部位的应力、变形等结果。对零件的设计和优化有很大的参考作用。正是因为上述优点，我在本设计中运用UG 来建立三维模型。再将此模型导入ANSYS软件来对其进行分析。关键词：传动轴，三维建模，ANSYS，动静态分析AbstractANSYS (finite element)packageisa multipurposefinite elementmethod forcomputer designprogramthatcanbe used tosolve the structure,fluid,electricity,electromagnetic fi
