| Abstract: | In this paper, the finite element analysis software （ANSYS） was applied to do the model analysis for the JJ225/43-K drilling machine derrick under natural condition and the infrequent earthquake of 8 on the Richter scale vibration list separately. The preceding 10 steps modal frequencies, the corresponding vibration modes of the derrick and earthquake affecting parameters were gotten including biggest unit of ess-strain of derrick. The results showed that the derrick can bear the destroying of earthquake of 8 on the Richter scale, so the structure design of derrick is reasonable. |
