| Abstract: | In this paper, a new finite element vibration model of the barrel mast has been developed, the vibration of the barrel mast is calculated with this model, and the results are discussed. The results are correct. The singularity elimination methods of space truss and frame structure are also analysed, and a new singularity elimination method has been developed. |
