| Abstract: | A mechanical mode of a hinged cantilever girder with two springs suspended is brought forward based on the actual structure of a derrick runway girder and is studied with dynamics in this paper. Having an example of TC80 derrick, many order natural frequencies and principal mode are obtained by finite element method. The result of the dynamic analysis has practical sense to the dynamic response analysis of the derrick. |
