【摘要】：单梁起重机广泛用于工厂、仓库、料场等不同场合,数量巨大。传统的设计分析方法中,是对每一台设计的起重机根据其尺寸参数,利用材料力学原理对其进行受力分析计算,在计算过程中不仅有着大量的简化处理,另外也会耗费大量的时间在手工计算上,其准确性得不到很好的保证。随着如ANSYS、ADINA、ABAQUS、MSC等有限元软件的发展,现在可以采用有限元软件进行建模分析,这样大大减少了手工计算量并提高了计算准确性,但是也要耗费大量的建模时间,另外对于不会有限元分析软件的设计人员来说,也是个很大的问题。所以研究并开发一套参数化的分析系统是很有必要的,让其提供良好的易沟通的人机界面,供使用者只要输入相关参数,就可由计算机自动完成模型的建立和应力、位移、模态、稳定性,动态等各种分析,并将结果友好的显示出来。这样的参数化分析系统将大大减少重复性的建模分析过程,并且由于引进了动态分析,比传统的静力分析更具可靠性,从而提高企业的设计分析的可靠性及效率,加快产品的研发,另外也可以被检测部门用来对单梁起重机的结构进行检测分析,只要现场操作软件即可。本文主要利用Visual C++开发工具将ANSYS的参数化技术结合在一起,开发出了一套单梁起重机的参数化分析系统,其主要研究内容如下： 1)利用APDL语言参数化建立两种主梁截面的单梁起重机的有限元模型,并编写相应的参数化加载、计算以及提取结果的APDL命令流。 2)进行了单梁桥式起重机的静力分析、模态分析、谐响应分析以及瞬态冲击分析等方面的研究。并编写相应的APDL命令流,以作为VC开发参数化系统的基础。 3)研究了VC6.0与ANSYS的接口技术以及相互之间的通信技术,利用VC对ANSYS进行封装。 4)利用VC结合ANSYS开发了一套集参数化建模,应力、位移、稳定性、模态、以及动态分析于一体的分析软件。
[Abstract]:Single-beam crane is widely used in factories, warehouses, material yard and other different occasions, a large number. In the traditional design analysis method, every crane designed according to its dimension parameters is analyzed and calculated according to the material mechanics principle. In the process of calculation, there are not only a lot of simplified processing, In addition, it also spends a lot of time on manual calculation, and its accuracy is not guaranteed well. With the development of finite element software such as ANSYS Adinan Abaqus MSC, the finite element software can be used for modeling and analysis, which greatly reduces the manual calculation and improves the accuracy of calculation, but it also consumes a lot of modeling time. In addition, it is also a big problem for designers who do not have finite element analysis software. Therefore, it is necessary to study and develop a parameterized analysis system, which provides a good human-machine interface that is easy to communicate with, so that the user can automatically complete the modeling, stress and displacement by the computer as long as the relevant parameters are inputted. Modal, stability, dynamic and other analysis, and will be friendly to show the results. This parameterized analysis system will greatly reduce the repetitive modeling and analysis process, and because of the introduction of dynamic analysis, it is more reliable than the traditional static analysis, thus improving the reliability and efficiency of enterprise design analysis. It can also be used by the inspection department to test and analyze the structure of single beam crane, as long as the field operation software can be used. In this paper, a parameterized analysis system of single beam crane is developed by combining the parameterization technology of ANSYS with Visual C development tools. The main research contents are as follows: 1) using APDL language to parameterize the finite element model of two kinds of single beam crane with main beam section, and write the corresponding parameterized loading, calculating and extracting the APDL command stream of the result. 2) the static analysis, modal analysis, harmonic response analysis and transient impact analysis of single girder bridge crane are studied. And write the corresponding APDL command stream, as the VC development parameterized system foundation. 3) the interface technology and communication technology between VC6.0 and ANSYS are studied, and ANSYS is encapsulated by VC. 4) A set of parametric modeling, stress, displacement, stability, modal and dynamic analysis software is developed by using VC and ANSYS.
