摘  要

 随着计算机软硬件技术的飞速发展，为工业产品的研发、设计、制造及性能试验提供了全新的工具和手段:虚拟现实技术(Virtual Reality Technology )、虚拟仿真技术(Virtual Simulation Technology )、虚拟试验技术(Virtual Experiment Technology )、虚拟试验场(Virtual Proving Ground),虚拟原形试验仿真技术(Virtual  Prototyping  Experiment  Simulation Technology)等新技术把人们从产品研发、设计、制造和试验的传统方式带入了美妙的计算机虚拟世界,在计算机上建立产品完备的三维实体模型，创建虚拟的制造工厂、虚拟的实验室运行环境，在虚拟的环境下完成各种测试、试验，评定未来产品的制造性能、装配性能、使用性能。从而极大地减少样机的试验制造次数，缩短产品的开发周期，降低开发成本。其中的虚拟试验技术，由于其可以部分替代现实世界中难以进行的试验，或者是费时、费力和费钱的试验，得到了人们越来越多的重视。有限元法是一种有效的数值计算方法，而ansys更是一款相对比较完善的有限元分析软件，运用ansys对吸附器和工字形梁模具进行分析可以有效的指导和修改设计。本文通过吸附器疲劳分析，分析了其结构的薄弱环节，以及疲劳强度。介绍了ANSYS疲劳分析的方法，通过例子说明了有限元分析在疲劳问题上的有效性。为其他类型疲劳问题的分析提供了参考。工字形梁模具的热分析则是ansys另一项功能，对于模具在熔料注入到产品成型过程中的温度变化的分析以及在这个过程中模具内部的等效应力场和等效应变场的分布，分析出模具在浇铸过程中的薄弱环节

Abstract
Computer software and hardware technology with the rapid development of products for industrial R & D, design, manufacture and provide a new performance test tools and instruments: Virtual Reality (Virtual Reality Technology), virtual simulation technology (Virtual Simulation Technology), virtual test technique (Virtual Experiment Technology), Virtual Proving Ground (Virtual Proving Ground), the virtual prototype test simulation technology (Virtual Prototyping Experiment Simulation Technology) and other new technologies to people from the product development, design, manufacture and test of the traditional way into the wonderful the virtual world of computers, computer product in a complete three-dimensional solid model, the creation of virtual manufacturing, virtual laboratory environment, in a virtual environment to complete various tests, testing, evaluation of the performance of future products manufacturing, assembly performance , the use of the performance. Thus greatly reducing the number of prototype manufacturing of test and shorten the product development cycle, lower development costs. The virtual test technology, in part because of its alternative to the real world it is difficult to carry out the tests, or time-consuming, laborious and costly testing, more and more people get attention. Finite element method is an effective numerical method, and more ansys is a relatively well-finite element analysis software, the use of adsorption and ansys-shaped beam analysis tool can effectively guide and modify the design. In this paper, fatigue adsorber analysis of its structural weaknesses, as well as fatigue strength. Introduced the method of fatigue analysis ANSYS, through examples of finite element analysis in the issue of the effectiveness of fatigue. For other types of fatigue analysis of the reference. Beam-shaped mold ansys thermal analysis is a separate function, for the mold in the molten molding material injected into the product in the process of analysis of temperature changes, as well as mold in the process, such as effects of the internal force field and the distribution of equivalent strain field analysis of the die casting process in a weak link in the
Keywords: ANSYS finite element analysis of fatigue strength of    thermal analysis
