摘要:
以客户提供的液化器设计结构草案和设计载荷为基础进行分析,对液化器下部带夹套的异形偏心锥体结构进行强度核算.首先利用三维建模软件SOLIDWORK建立实体模型,然后将模型导入有限元分析计算软件ANSYS中定义单元、划分网格和施加载荷 ,再进行有限元内压静载荷分析和外压屈曲稳定性分析,最后依据国家标准JB4732-1995(2005确认)中的相关评定规则对分析结果进行评定.对结构草案中弯曲应力超过标准要求的不连续结构区域进行结构改造,降低弯曲应力,使液化器下部锥体的最终设计方案能够满足国家标准的要求和客户的要求.
Abstract:
The structure drafts and loading data of devolatilizer provided by owners were analyzed, and the strength of abnormity eccentricity cone with jacket on bottom of devolatilizer was calculated. Solid model was created by SOLIDWORK, then the model was introduced into ANSYS to define elements, divide networks and apply load. The calculation of static internal pressure and external pressure bucking was performed. The results were assessed by JB47321995(2005 confirmed). Local structures which bend stress were larger than allowed were amended so that the bend stress was reduced. The amended structure meets the requirements of JB4732 and owner.
