| Abstract: | It is difficult to research the dynamic response of rock in hole bottom during drilling.
In this paper, a new finite element analysis method-general function transformation
method is presented. For the special core function,the computation formula is established and computation steadiness is researched. Through theoretical analysis and computational instance,the method has shown the advantage of higher accuracy,less operation than or-diary method. The method is also suitable for the dynamic analysis of engineering structure. |
