修井机井架的结构优化设计

<title>Structure design and optimization analysis of workover rigs

运用有限元软件ANSYS建立计算模型,对修井机井架进行结构设计和优化分析。结果表明,井架的结构设计对井架的受力分布起着至关重要的作用,合理的结构设计可以提高井架的安全性;对井架进行局部优化可以节省材料和减轻井架的自身质量,有利于提高井架的安全性和经济性。

<Abstrcat>?Structure design and optimization analysis and setting up computational models to the workover rigs using the finite element software ANSYS are introduced The analysis results suggest that the structure design of oil derrick plays a important role in the distribution of force in the oil derrickThe reliability of oil derrick can be improved by the reasonable design of structureLess materials will be required and its weight can be reduced by partial optimization to the derrick, which is beneficial to improve the reliability and economy of oil derrick
