유연관의 효과적인 동적거동 해석을 위한 모델링 방법 비교연구

Abstract

The efficacy of various well-established dynamic modeling schemes for flexible pipes, as flexible multibody systems with large displacement, has been studied in this paper. Finite difference method with Lumped-mass model and the Substructuring formulation have been introduced for comparison purposes, with application to fishing rod problem using cantilever beam. Pros and cons of methods are discussed for flexible pipe through the results of various numerical analyses.ing formulation have been introduced for comparison purposes, with application to fishing rod problem using cantilever beam.
