摘要
本文应用有限元方法对一改装的5OOm装钻机开式井架进行了结构分析。针对开式井架的特点,提出了“虚杆”的处理方法 计算结果表明,改装后的井架在可能的荷峰值范围内强度是足够的。
This paper analyses a refit open type oil derrick of a 500m towing drilling machine for the strength with the finite element method.According to the characteristic of this derrick the writer advancesa handing method - imaginary bar. The results of compulation shousthat this derrick is safe for the strength in possible range of the load peak value.
