【摘要】：立体货架作为现代的仓储设备之一,具有存取效率高、自动化程度高等优点,可以减少劳动人力成本,产生大量的社会和经济效益。货架部分作为立体仓库载重受力的主体,对其强度刚度以及制造成本等进行优化和设计已成为近年来较为热门的研究内容。针对目前在立体仓库货架进行有限元分析求解过程中存在的步骤繁琐、不可逆向修改设计等缺点,本文在传统设计方法的基础上,结合参数化理论和相关有限元分析理论,采用计算机辅助工程的手段,以某型号自动化立体货架为分析对象,利用对有限元分析软件ANSYS的二次开发技术,编写APDL参数化设计语言,解决常规建模过程中的建模时间长、建模过程繁琐和模型利用率低等问题。借用Visual Basic6.0软件的界面设计平台,设计相关窗体结构,开发了一个能应用于立体仓库的自动参数化有限元建模与分析系统,将内部输入的参数顺利录入到外部APDL文件中,并实现后台调用ANSYS批处理模式进行针对立体货架的分析和计算。应用结果表明,该系统可按要求赋予自定义梁截面并自动实现货架的快速建模,完成相应的有限元求解,同时提取计算结果,得到计算云图,为设计人员提供直观、生动、准确的参考,极大提高了分析效率。同时,也可将该系统原理和方法推而广之,适用于改进各类立体货架货架,甚至其它类似工业产品的设计。
[Abstract]:As one of the modern storage equipment, the three-dimensional shelf has the advantages of high access efficiency, high degree of automation and so on. It can reduce the labor cost and produce a large number of social and economic benefits. As the main force of the three-dimensional warehouse, the optimization and design of the strength and stiffness and manufacturing cost of the shelf has become a hot research content in recent years. In view of the shortcomings in the process of finite element analysis and solving in the shelf of three-dimensional warehouse, such as tedious steps and irreversibly modified design, this paper combines parametric theory and relevant finite element analysis theory on the basis of traditional design method. By means of computer-aided engineering, taking a certain type of automatic three-dimensional shelf as the analysis object and using the secondary development technology of finite element analysis software ANSYS, the parametric design language of APDL is compiled, which can solve the problem of long modeling time in the process of conventional modeling. The modeling process is cumbersome and the model utilization is low. With the help of the interface design platform of Visual Basic6.0 software, the related form structure is designed, and an automatic parametric finite element modeling and analysis system is developed, which can be applied to the stereoscopic warehouse. The internal input parameters are entered into the external APDL file smoothly. And realizes the background call ANSYS batch processing mode to carry on the analysis and the calculation for the three-dimensional shelf. The application results show that the system can give self-defined beam section and automatically realize the rapid modeling of shelf, and complete the corresponding finite element solution. At the same time, the calculation results can be extracted and the computed cloud map can be obtained, which can provide the designers with visual and vivid. Accurate reference greatly improves the analysis efficiency. At the same time, the principle and method of the system can be extended to improve the design of all kinds of three-dimensional shelves and other similar industrial products.
