Abstract:This paper researches the relationship 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 evaluation the bearing capacity of the derrick is presented by testing frequencies of under different loads action. This method is applied to detection and evaluation of derrick-inuse.
Keywords:derrick  dynamic parameter  bearing capacity  safety evaluation
