摘要
采用MSC/Nastran对扒杆结构在4种工况下的强度进行了有限元分析,介绍了有限元模型建模方式、计算工况以及许用应力的计算,并对计算结果进行了分析。结果表明扒杆结构各主要构件强度均满足规范要求,并可作为改进设计的参考。
The derrick structure strength under 4 cases is carried out by MSC/Nastran. The techniques of establishing model, load cases and the calculation of admissible stress are presented, and the results are analyzed. The results show that showed that main components strength are meet the rule, and it can be referenced to improve the design.
