변단면 Cantilever보의 동력학적 해석에 관한 연구 ( Dynamic analysis of Tapered Cantilever beam )

Dynamic analysis for Variable cross section elements has been estabilished through out the past several years, TAPERED CANTILEVER BEAM used often in actual field work. This study is aimed to make a comparison with the theoretical solution made by H.H.Mabie & C.B.Rodgers, and the numerical solution produced by numerical method, F.E.M and TRANSFER MATRIX METHOD here I propose. The results are as follows. 1. Numerical solutions made with both F.E.M and TRANSFER matrix method are very fittable for finding the dynamic characterestics. 2.The minimum percentage error is 2% below in variable parameter 2, used 3-4 elements.
