中文摘要:
      为了提高分段吊装工艺结构强度的计算效率,本文将参数化思想应用于分段吊装方案的有限元分析中。首先采用结构参数化方法快速建立各种分段结构的有限元模型,然后对眼板、吊绳、工况等三类吊装工艺信息进行参数化处理并提出了针对不同的吊装工艺的快捷仿真方法。最后实现了基于参数化分析方法的典型双层底分段的平吊和翻身的结构强度分析。
英文摘要:
      In order to improve structural strength calculation efficiency of block lifting technology, parametric concept is applied to finite element analysis of block lifting schemes. Firstly, finite element models of various blocks are established quickly by using the structural parameterization method. Then, the three types of lifting process information, such as lifting-eye, lifting rope and working condition are parameterized and a rapid simulation method for different lifting processes is proposed. Finally, based on the parametric analysis method, the structural strength analysis of the horizontal lifting and turning over process of the typical double bottom block is accomplished.
