Modal Analysis of Drilling Machine DerrickOA
Modal Analysis of Drilling Machine Derrick
In this paper, the finite element analysis software ( ANSYS ) is applied to the modal analysis of a ZJ30/1700CZ 's drilling machine derrick under a natural condition and a loaded condition, respectively. The preceding nine step natural frequencies and the corresponding mode shapes of the derrick are calculated. By means of the comparison of the natural frequency of the derrick with the design work frequency of the drilling machine and the analysis of the step mode shape of the derrick, the drilling machine derrick structure design is proved to be correct.
