Publish Date: 10 April 2014

摘要: 利用solidworks2013建立井架模型,导入ansys14.5对大风额载工况与模态进行了有限元分析。分析表明,井架在8级风速额定载荷下强度刚度均满足安全使用要求,关键部位焊缝强度储备充足。此外,通过对井架的固有频率与钻机工作频率的比较,并对各阶模态主振型的分析,得出该钻机井架结构设计合理的结论。

Abstract: The derrick model was established based on solidworks 2013, and ansys14.5 was introduced to make the finite element analysis on the rated load and model in strong winds.The analysis indicates that all the strength and rigidity of the derrick meet the requirement of safe use under the rated load in 8th-force wind with sufficient weld strength reserve of the key parts.By comparing natural frequency of the derrick and working frequency of the drilling machine, the analysis on the main vibration mode of each modal comes to that the derrick structure of drilling machine is designed reasonably.
