FE Simulation of Bolt-up Process for Press-Retraining Bolts of HTR-PM Pressure Vessel
-
摘要: 用结构分析软件ADVENTURECluster对高温气冷堆(HTR-PM)一回路压力容器42个M88承压螺栓的分组、分阶段预紧过程进行数值模拟。预紧分为7组2个阶段进行。数值模拟结果表明:不同组螺栓不同阶段的预紧,对其他螺栓的预紧力会产生不同的影响。Abstract: The reactor pressure vessel FE model with 42 M88 bolts is built in this study by ADVEN-TURECluster.These 42 bolts are divided into seven groups,and there are two steps in the bolt-up process.The simulation results show that every bolt-up step will make different influence to different groups of bolts.
