摘　　要：为了提高分段吊装工艺结构强度的计算效率,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3类吊装工艺信息进行参数化处理并提出了针对不同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.经过实例验证该参数化方法避免了大量重复性工作,有效地提高了分段吊装有限元建模和强度计算的效率.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, 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 parameterization analysis method,the structural strength analysis of the horizontal lifting and turning over process of the typical double bottom block is accomplished.According to an example, the parameterization method is verified to avoid a lot of repetitive work, and effectively improve the efficiency of finite element modeling and strength calculation of block lifting.
