摘要:: 用振动理论研究井架结构固有频率与作用载荷的关系, 并对现场在用井架模型进行了有限元数值分析, 得出井架结构作用载荷与其固有频率平方之间的线性关系, 提出测试井架在零载和有载作用下的固有频率来评定安全承载能力的方法, 并应用此方法对现场在用井架进行了测试和安全评定。

Abstract:: This paper studies the relat ionship between frequency of derrick structure and load acting on it by using vibration theory, and the numerical simulations analysis for derrick model- in- use is carried. So the linear relationship between the load acting on the derrick and the square of the basic frequency is deduced. On this basis, a method of evaluating the bearing capacity of the derrick is presented by test ing frequencies under dif ferent load actions. This method is applied to detection and safety evaluation of derrick- in- use.
