使用ANSYS自动接触技术的方法文档格式.docx

1、装配体的分析模拟是公认的最尖端的CAD/CAE技术之一,这项技术使得人们得以精确的预测一个多零部件的结构的性能。传统的,也是最直接的装配方法是先简单的导入装配体的各个零部件,确定它们的空间相对位置,然后人为地确定各零部件在整个装配体中的接触关系,建立接触单元。此过程在其他CAE软件中须采用手工方式完成,不仅需要漫长的虚拟整机建立过程,同时,还需要工程师对结构的各项指标、限制、风险全面的了解。每一个有经验的有限元分析工程师都知道,没有任何两个接触问题是完全一样的,装配问题的复杂性在某种程度上肯定了ANSYS在这个领域的成就ANSYS可以对各种不同的接触问题进行非常好,而且简便的模拟。一个装配体的

2、ANSYS有限元分析过程可以简单的归纳为, 建立模型并划分网格 识别零部件相互关系 施加边界条件以及环境参量 求解并复查结果 事实上在ANSYS默认的设定中,当一个装配体的CAD模型被倒入的时候,接触关系已经被自动的探测了,而接触区域被指定为面/面culture and entertainment venues, fitness centers, has a good ecological environment, job security measures）, these requirements are very straightforward, specific standards, a

3、lso has a clear direction, more easily by a superior examination. Poverty assessment is to look at the per capita net income of the poor end of 2015 standards is . . Yuan, higher standards is poverty. Superior acceptance to entrust a third party institution from HouseImplementation. After acceptance

4、, also through spot checks, visits, telephone surveys looking activities. This means that our achievements have been recognized by the poor for poverty alleviation through acceptance, which we put forward higher requirements for poverty eradication. Therefore, the County Office for poverty alleviati

5、on to evaluation efforts in this regard. To implement the grid management model, integrating poverty alleviation into grid management, and make a heart activity combined package of leading cadres implement monitoring systems for poverty alleviation, each poor households identified a package cost. In

6、 this regard, you can design a form, indicating the poor basic causes, current income, poverty, support measures, implementation of support measures, through helping income, annual revenue. From now on, protection officers working households, household-by-place. When the examination, which the poor

7、dont have time to get out of poverty, and holding people accountable. Third, on environmental protection in construction of ecological civilization is the focus on one of the six battle this year. Xian Wei proposed to build green mountains and beautiful, happy and harmonious new . . Target, which is

8、 the basis of environmental protection. Do well environmental protection work, we keep the side of the mountains, nor to the masses to create a suitable for residential and business suitable for swimming and raising living and working environment. Last year, we got good grades the environmental work

9、, atmospheric index ranked 4th in the city to obtain eco-compensationaccording to project needs, in accordance with the channel, use the same, and use principle, the implementation of project planning, funding and manpower arrangements, avoiding duplication of inputs and waste of resources, effectiv

10、e integration of poverty relief funds . Here to remind everyone that bundle integration-related funds, aims to concentrate financial resources for big undertakings. Authorities do not think that has less autonomy, pursuing the deregulation of work. This year on the amount of funds on fighting for th

11、e departments concerned to increase over the previous year . and . respectively. In this regard, the financial Department to dispatch in a timely manner, analyses relevant departments strive for. （E） to implement the poverty assessment responsibilities. Of village-level evaluation is very clear, tha

13、拓宽了可以模拟的接触类型。在接触关系控制设定中, 全局属性,包括自动接触探测的基本设定,以及高亮显示的接触区域的透明度设定,这些设定将会影响所有的接触区域。接触区域控制,包括接触属性浏览,区域接触类型设定,以及其他的一些高级控制选项,例如设定接触模拟方程,法向刚度,热传导设定,以及pinball区域设定等等。更加详细地,自动接触探测的基本设定包含,容差设定（Tolerance setting）,即容差类型以及容差值的设定;接触探测的种类设定（例如设定探测面/面接触,面/边接触以及边/边接触）等;接触探测种类优先权设定（例如设定面/面接触优先于其他种类的接触）等。在接触区域控制的接触类型设定中,

14、ANSYS可以模拟如下的多种接触类型, 固结（Bonded）,即完全绑定,无摩擦也无滑动。不分离（No separation）,和固结类似,不过在小范围内允许无摩擦的滑动。无摩擦（Frictionless）,部件之间摩擦系数为0,允许法相分离。粗糙（Rough）,与无摩擦类型相似,只是部件之间不允许接触滑动。culture and entertainment venues, fitness centers, has a good ecological environment, job security measures）, these requirements are very straigh
