T8钢圆柱体水淬过程温度场模拟 摘要: T8模具钢属于抗冲击碳素工具钢、冷作模具钢、淬硬型塑料模具用钢，该钢无网状碳化物析出倾向，塑性、韧性优于T10A钢，适用于制作较大截面的模具。重载模具采用T8模具钢，进行预先调质球化处理，效果较好。该钢可加工性好，价格低廉，来源容易，但缺点是淬透性低，耐磨性差，淬火变形大。 本文将采用ANSYS有限元分析对T8钢进行热处理过程模拟，热处理过程计算机模拟具有速度快、效率高、结果形象逼真、能综合全面反映热处理过程中各种变化规律的特点。与试验研究相结合，可以极大地拓展实测数据提供的信息，完成试验研究很难做到甚至不能做到的工作。国内的许多专家和学者运用MARC、ANSYS 关键词：T8钢，ANSYS有限元分析，温度场 T8 steel cylinder water quenching process temperature fieldsimulation Abstract: T8 tool steel belongs impact carbon tool steel, cold work tool steel, hardened plastic mold steel, the steel mesh carbide precipitation no tendency ductility, toughness than T10A steel, suitable for the production of a large cross-section of the mold . Overloaded mold using T8A mold steel, quenched and tempered ball pre-treatment, the better. The steel machinability good, inexpensive, easy to source, but the drawback is the low hardenability, wear resistance is poor, large deformation hardening. This article will use the ANSYS finite element analysis of T8 steel heat treatment process simulation, heat treatment process computer simulation has speed, high efficiency, the results of vivid, heat treatment process can be integrated fully reflect changes in the characteristics of various laws. Experimental studies with the combination of the measured data can greatly expand the information provided to complete the tests do not even difficult to do research work. Many experts and scholars in the domestic use of MARC, ANSYS software for reality to simulate the heat treatment process, but also made a series of satisfactory results, simulation results and guidance on the production practice Keywords: T8 Steel，ANSYS finite element analysis，Temperature field 目 录 1 绪论 1 1.1 T8钢的基本结构和淬火工艺基础 2 1.1.1 T8钢的基本结构 2 1.2 淬火工艺基础 3 1.3 淬火后组织分析 4 2 ANASYS10.0热分析 5 2.1 ANASYS软件介绍 5 2.2 热分析的目的 5 2.3 热分析的基本理论 5 2.3.1基本符号与单位 5 2.3.2热传递的方式 6 2.3.3热力学第一定律 7 2.3.4热传导控制微分方程 7 2.4 ANASYS稳态热分析 8 2.4.1热载荷和边界条件的类型 8 2.4.2稳态热分析基本步骤 9 2.5 ANASYS瞬态分析 11 2.5.1瞬态热分析特性 11 2.5.2时间步长设置 11 3 T8钢圆柱体有限元分析 1
