【Abstract】 In this paper, the CAE technology is applied to the static analysis and the modal analysis of ZJ30/1700CZ’s drilling machine derrick under load and without external loads separately, so that the scientific basis for rational design the drilling machine derrick structure is provided. By analyzing and calculating, we can get the following conclusions: The static strength of the derrick is enough; the natural frequency of the modified derrick and the working frequency of drilling machine are differed greatly, so the resonance can not occur in operation; the modified derrick structure design is approved to be correct.更多还原
