| Abstract: | In this paper, firstly, the natural frequencies and modes of A' form derrick are analysed. Then,using the random perturbation finite element method,the one-order and two -order sensitivities of the derrickare calculated when the servel structural parameters of the elements are changed randomly. Finally, the randomstructural eigenvalues' concrete expressive formula of the derrick are given out. |
