摘要
为了研究在建或拟建日光温室的结构性能,对日光温室进行有限元分析,提出了利用ANSYS提供的二次开发工具APDL,并用VB开发出参数输入图形化界面的日光温室结构有限元分析程序系统,自动完成日光温室结构有限元分析过程。以哈尔滨市某一无立柱圆弧形前屋面型日光温室为实例调用了该二次开发系统,得到相应结构变形图和应力图,通过VB结果后处理模块提取出计算结果数据,分析得出日光温室结构在50年一遇的极端天气下仍是安全可靠的,这证明了该二次开发系统的可行性。该系统有利于用户方便快速地对日光温室结构进行有限元分析,减少了日光温室结构研究与设计的工作量,提高了研究效率。
In order to study the structural properties of solar greenhouse, finite element analysis was conducted. The use of secondary development tool APDL provided by ANSYS was proposed, and greenhouse structure parameter input graphical interface finite element analysis program system was developed by VB, greenhouse structural finite element analysis was automatically completed. With Harbin City as an example, the corresponding structural deformation and stress diagram chart were obtained, the calculation result data was extracted by VB results post - pro- cessing module, it was found that the greenhouse structures under the extreme weather is still safe and reliable. The system helps users quickly and easily to conduct finite element analysis on greenhouse structure, reduce the workload of the greenhouse structure and design, and improve research efficiency.
