ANSYS软件是融结构、热、流体、电磁、声学于一体的大型通用有限元分析软件，本文利用ANSYS软件完成了对凝固铸件的热分析，磁螺线管驱动器的电磁分析，以及角架结构的静态分析，加深对ANSYS有限元分析的认识。 关键词：有限元分析ANSYS1 ANSYS软件简介ANSYS是一种广泛的商业套装工程分析软件。所谓工程分析软件，主要是在机械结构系统受到外力负载所出现的反应，例如应力、位移、温度等，根据该反应可知道机械结构系统受到外力负载后的状态，进而判断是否符合设计要求。一般机械结构系统的几何结构相当复杂，受的负载也相当多，理论分析往往无法进行。想要解答，必须先简化结构，采用数值模拟方法分析。ANSYS软件是融结构、热、流体、电磁、声学于一体的大型通用有限元软件，可广泛的用于核工业、铁道、石油化工、航空航天、机械制造、能源、汽车交通、国防军工、电子、土木工程、生物医学、水利、日用家电等一般工业及科学研究。该软件提供了不断改进的功能清单，具体包括：结构高度非线性分析、电磁分析、计算流体力学分析、设计优化、接触分析、自适应网格划分及利用ANSYS参数设计语言扩展宏命令功能。ANSYS软件主要特点：1). 唯一能实现多场及多场耦合分析的软件 2). 唯一实现前后处理、求解及多场分析统一数据库的一体化大型FEA软件 3). 唯一具有多物理场优化功能的FEA软件 4). 唯一具有中文界面的大型通用有限元软件 5). 强大的非线性分析功能 6). 多种求解器分别适用于不同的问题及不同的硬件配置 7).支持异种、异构平台的网络浮动，在异种、异构平台上用8. 多种自动网格划分技术 8). 良好的用户开发环境
